I voted for Ajido-marujido. I always did love that taru. I mean we get to play with him in the past as a child, then in present. Wouldnt mind taking the present Ajido to visit his younger self in [s]. That or take him to Adoulin for some sorta quests.

Tho reading some posts here. Karaha-Baruha along with his kids would be awesome as a quest...
Tho tbh, I wouldnt mind seeing Zonpa-Zippa come out of hiding and return to life in Windurst some.
