We will address these assuming you survive your trip to the ship. In the meantime feel free to ask Elayu your question.
**screaming over the rushing wind**
So mightly celestial griffin Elayu, we are in what the humans call a pickle. Some of the crew might already be possed by Oni. In which case they might try to arrest me, or kill me. That would be bad, in that case fly back to the temple and get help. The evidence we overheard said "released at dawn" so it's not a sure thing.
I know the Lord Tulist is possesed, and i'm a young high noble that has yet to do anything worth while for our country, The crew, and the captain are probably not going to listen to me over Lord Tulist. But I have a plan, I have an item that allows my to illusion myself. If I appear to look like Lord Nisoru, light of Stasis, would you back me up? They can't deny someone who appears to be Master Nisoru when his mighty mount is also with him. I only need the crew to detain Lord Tulist and search him, there should be a red crystal somewhere on him.
