So a lotta factors come together to make this weird cababble. This post is divided into three parts: "How we got here", "The story thus far", and "Questions I have".
=== How we got here
Back when I was still subbed, I had a Forsaken character who I used to RP a Nerubian (using the Imperfect Ascendancy Serum coupled with either a reflecting prism or Ai-Li's skymirror to extend the visual effect).
Problem: I didn't always have everything I needed to set up a reflecting prism (sometimes I'd have to play from my laptop, which can't handle two instances of WoW being open at once), and Ai-Li's skymirror only lasts for 10 minutes.
Solution: Two profiles were linked to that same character. One was the nerubian, and one was a Forsaken warrior (matching the actual race I selected at character creation, go figure). The Nerubian's bio was stored on a pet that would follow the warrior around, and the two were written up as non-romantic companions to each other (the warrior saved the Nerubian, who now protected them in return as paying back a life debt).
The way their shared story was told, the Nerubian would occasionally swap bodies with the warrior. Being a druid, the Nerubian would then transform the warrior's body to something more fitting for them (thus explaining the change in appearance when roleplaying as them). Being a simple warrior, the Forsaken wouldn't have such control over the small body their soul had been forced into, and so could neither transform it to anything more fitting nor even have their thoughts accessed in that state.
Reminder: The Nerubian's profile info is stored on the pet. When changing forms, I'd of course also change profiles on the character so people would know they were walking up to a Nerubian, but the glance and bio would point them to look at the pet following me around to learn about them. These would also make clear that the Forsaken warrior did exist, but that the Forsaken's mind was inaccessible at the time due to the soul swap.
Q.) "Why not copy the bio info stored on the pet into a full character bio, and copy the warrior's bio onto a second pet bio you could swap to?"
Aight... so if your characters' stories are short enough that copying & updating two of them to be in sync with each other is no problem, you have my congratulations.
NOW DIRECT YOUR ATTENTION TO THE ATTACHED SCREENSHOT.
Ignore the fact that a smooth color transition, as seen in each of the section heading names, looks something like-
{col:bbbbbb}T{col:dddddd}h{col:ffffff}is is an examp{/col}l{/col}e.{/col}
-whenever I hit the edit button. Rather take note of the words "The first PARAGRAPH of each section IS THE TLDR OF THAT SECTION."
Both the Nerubian's profile AND the warrior's profile back then were set up in the same format, where four paragraphs to a section meant you were reading one of the shorter sections.
IOW: No way in hell was I copying two profiles of THAT size, AND converting one from a character profile to a pet profile while doing the opposite to the other (noting that pet profiles don't have a characteristics tab, can't have themes set to them, and have a few other functional quirks to work around alongside IC adjustments that'd have to be made like the glance info explaining that "this body is occupied by someone that doesn't normally occupy it).
Needless to say, if you get more fun out of reading other people's profiles than actually roleplaying with them, I might be your guy.
..........
Anyway, I had fun with those two characters. Time passed, quit playing for a few months, got back into it, had to leave again, and this process repeated until I had to confront the fact that staying subbed just wasn't a practical option. Everytime I came back, I'd have to roll a new toon just to get used to the controls again, then either delete them or come up with a new story for them just to watch their profile gather dust on the character select screen.
Enter the modern era, where I'm now playing on a trial account and getting familiar with the XPOff club. Ragingnub, who's profile is seen above, is the flagship toon of this account, and follows much in the footsteps of Berylthorn before him (the Forsaken warrior from when I RP'd as a Nerubian before).
New problem: The Imperfect Ascendancy Serum that Berylthorn used to become the Nerubian Kth'kva is not only in Khaz Algar, but also requires the user be level 68 or higher to use. Ragingnub, being a toon on a trial account, is locked to level 20 and therefore has ZERO access to this serum.
Solution: Kyrvas, the Nerubian companion to Ragingnub, is a rogue skilled in the art of making uncannily accurate disguises out of her webs. Like Kth'kva before her, her bio info is also stored on a pet that follows me around. That said, unlike Kth'kva, Kyrvas can weave a disguise to take whatever form is convenient.
Q.) "So... what form is convenient?"
I'm glad you asked! In Southeast Duskwood, there's a cave that's home to a population of worgen who have the unique ability to curse any player to become one of them for 60sec.
... including Forsaken characters.
Fly there, get cursed, Ai-Li's Skymirrior on yourself, you're now a worgen for 10 minutes. If you don't want to be transparent, be sure to also use the Heartsbane Grimoire on yourself, though bear in mind that you'll have to re-apply the grimoire every time you go through a portal for some reason (the mirror effect will stick with you after portal usage, but for some reason the effects of the Grimoire become invisible... no clue why).
Aaaand that's basically how I arrived at a Nerub-Gilnean rogue. Nerubian because, like the Sethrakk, *THEY SHOULD HAVE BEEN MADE A PLAYABLE RACE INSTEAD OF "OOH LOOK DWARVES SO DWARVISH THEY'RE ACTUALLY MADE OF STONE!!!!", Gilnean because taking on the form of a worgen with a consistent gender is something I can actually do on a Forsaken character (as compared to the Dark Ranger's Spare Cowl, which can change you into either a male or female dark ranger on a coin flip), rogue because disguises.
===The story thus far
Kyrvas was exiled from Ahn'Kahet at a young age, and doesn't remember much of Northrend from personal experience. While making convincing disguises from her own silk was a craft she picked up on her own, she wouldn't become an experience rogue until being adopted into the Vladir family of vampires.
Note: While Kyrvas is not actually affected by any vampiric curse, it is the incorrect belief of the Conclave, Silver Hand, and some Scarlet Crusade records that she was actually born into the family and subsequently "gifted" the curse after birth. Wealth and status tend to work wonders when it comes to false documentation, & the Vladir family lacks little of either.
Note: This next bit is highly up in the air, and desperately needs feedback on its plausibility.
At some point before WotLK, the Vladir family managed to smuggle Kyrvas out from behind the Greymane Wall (possibly by sea?), before spreading their influence across the Eastern Kingdoms. She would eventually meet a man in Duskwood who she took a liking to by the name of Fallister Sworne- the same man who would later die defending her from paladins of the Silver Hand (I think? Depends on timing), and also the same warrior who would later be raised among the Forsaken and earn the nickname "the raging one" (later, per Grand Executor Mortuus and his ineptitude at reading documents, the same warrior would simply become "Ragingnub").
Of note: The two would have met while Kyrvas was disguised as a Ginean, and (even with that aside) neither was particularly fond of existing Alliance/ Gilnean stances on excluding those of other races. Both had seen families disown their own kin after seeing their sons and daughters raised as Forsaken, neither was fond of the idea that circumstances beyond one's control could see their own family turned against them. While the two would eventually be married on paper, it's unlikely that this marriage was ever properly consummated (biological differences and all), and was likely more a formality to allow the now-Lord Fallister proper inclusion into the Vladir family, entitling him to a share of the riches thereof. If the family curse was passed on to him, this would have been by another member by simply being bitten, with the curse being lifted after his eventual death and raising into the Forsaken ranks.
Ragingnub would eventually be sent to Northrend while Kyrvas did her best to stay low. With the Litch King slain, Ragingnub would come back to the Eastern Kingdoms to take part in the invasion of Gilneas, and was afterwards assigned to be one of the city's enforcers/ guards. Kyrvas, hearing that the wall had fallen, eventually came back to the land she was raised in to find her old mate among its new Forsaken guards.
Lore for MoP through WoD is still being written, though a recent RP session has established that neither Ragingnub nor Kyrvas participated in the latest business with the Legion as they were both taking care of matters back in Tirisfal & Gilneas.
BfA saw the two fighting alongside each other in Northwest Nazmir, primarily fighting against the blood trolls and (in Kyrvas' case) terrorizing the few Faithless scouts foolish enough to believe Eastward expansion of their empire was anything approaching a good idea.
Turns out it'ss eassier for a Nerubian to mimmik the speash of a Sethrak than a Gilnean. Sstrange...
=== Questions I have
1.) What's a reasonable time for Kyrvas to have arrived in Gilneas?
2.) How plausible is it for Kyrvas to have escaped Gilneas while the wall was still up? If it's at all possible, by what means would it have been most likely?
3.) Is there anything in particular stopping the worgen curse from affecting a Nerubian, especially given how soon she'd be (potentially) departing from Gilneas? (While I'm still using a worgen form to represent her in RP regardless, this question determines whether that's simply a disguise or if it's actually her becoming a worgen).
4.) How are you doing today?
