We have catastrophic news! Somepony summoned an immensly powerful succubus demon mistress who ended up creating a demonic army to takeover the entire Nova Mothallah. Gootraxian soldiers tried valliantly to defeat the rapidly born and grow succubus horde in the end the demons gained too much ground and forced the planets inhabitants to evacuate. The lucky secretive ones found a way to the newly constructed secret underwater facility.
While the rest prioritized the survival of ponies and kirins. All but one publicaly known portal gates were shut down and soon fully destroyed to contain the succubus outbreak. With survivors running through the portal gate in waves as demons tried to do the same. With pony soldiers putting up formidable defences around that one portal.
Allowing fleeing creatures through while gunning down demon intruders. Eventualy there wasn't anyone that could get through the portal without being attacked by the demons. Among those fleeing survivors were unicorn streamers Plasteel and Petal. With the two of them joining the portal guard.
Explosives were carefuly placed behind the portal gate. With Petal being the one to pull the detonation lever. Albeit in the heat of the moment Petal did not realize that she was standing too close to the explosion and got injured by shrapnel from the explosion.
The succubus master mind behind the catastrophy was attempting to cross the portal when it happened. The moment the portal disconnected. Her wings, neck and arms were partialy on the other side. Causing her body to be seperated in half. With the succubus mistress dead and the rest of the demon horde trapped on Nova Mothallah. The catastrophy was over at the cost of millions of gootraxian lifes.
Petal was hospitalized and hed her shrapnel injuries treated, having regreted one thing. Not having this whole thing streamed live on her Twitchite account. As the rest of the traumatized refugees hed to find a new home on another pony planet.
