Now obviously the only trusts we know about so far are the MSQ scions, but once the system is in place I figure it's pretty likely the same AI will be applied to other NPCs, so which NPCs would people like as trusts?

My biggest pipe dream trust would be Alpha as a reward for the Omega storyline. Probably unlikely since he doesn't have that many animations and his ending was set up for him to adventure on his own, but I can dream.

More realistically I'd like to see the back-room scions like Hoary Boulder and Arenvald given the trust treatment later.
