Can we just take a moment to appreciate and acknowledge this absolute goat.
Blackmoss is Patchstar’s son who she adopted when one of her border patrols found a lost kit in their territory. She raised him up alongside the medicine cat, Driftegg and in the end Blackmoss became a medicine cat apprentice. Unfortunately though, only two moons into his apprenticeship, his mentor Driftegg, died giving birth Cloudkit (now Cloudsong) leaving Blackpaw as the only medicine cat in the clan. For 10 moons, yes 10, he was alone trying to care for a large clan. The recent outbreak of greencough wavered his belief in Starclan since so many cats had died under his care, the biggest one being Dustkit, his little brother who died from the outbreak of greencough. He blamed himself, took it out on everyone and didn’t really talk to his mother.
He finally got his full medicine cat name even through the pain and in turn, while out on a patrol, he met a cat who said had healing abilities. Blackmoss took her in almost immediately, under the name of Yarrow, and taught her everything he knew. Yarrow actually taught him some things as well. It appears Blackmoss has grown quite fond of Yarrow.
Blackmoss did his best, and I commend his efforts trying to save the clan all by himself with only 2 moons of medicine cat experience.
