Hidden Character

Has anyone found the hidden character? I have the spear thing for them but haven't found them yet.

Found Him! It's Gauly. He is at the Inn in Tigris City. You have to pay him 20000 Tez to have him join you. Sheesh.

I had no idea we could do that. He did go along with one mission and I tried to equip him with a different weapon, but wasn't able to. Thank you for that info

And where do you get 20,000 tez? I've spent all my money on upgrades for the characters and healing items. Everyone is armed and equipped with the best, but that doesn't leave me much money. Not even if I sell all the extra stuff I have

Is there a secret cave with money somewhere?
