Wait, your version of the goat isn't a dimensional counterpart of the lamb?

They aren't! In my AU, Goat was picked by Shamura to be a champion of the Bishops in case Narinder ever sent a vessel against them who was an actual threat. After a period of training with Shamura, Goat was put into stasis and hidden within Shamura's crown, with the intent to summon them when needed. Unfortunately, with Shamura's condition, they forgot they had a Goat secreted away, and it wasn't until the devotion left within the Crown to sustain Goat ran out and they were ejected that Goat's presence became known. (Lamb took the crowns from the Bishops upon defeating them in my stuff)

So Goat wakes up in what from their POV is a far distant future, one where their Master is Crownless and there's now a Lamb in charge of everything. Rough wakeup for Goat!

I see, so the goat was basically made to be a weapon to use against the red crown. I wonder if their first instinct upon meeting the lamb was to attack on site. I would imagine others, possibly Shamura themselves would have to intervene as i don't think lamb would be able to get the goat to stop by herself. Still though, what an unfortunate fate, bred and raised to be no more than a weapon and sealed away, only to awaken in a world where such a weapon is no longer needed.
