I need you guys’ help.

I need you guys’ help. I’m working on the kalashtar class for my Eberron conversion, and a core bit of the class is a move I’m calling “Burdened With Glorious Purpose”. It’s a mix of the Paladin’s quest and the Survivor’s eternal mark, in that you choose a purpose, some boons, and some vows, but at character creation. I’m looking for help with coming up with the boons and vows: what do you think that a kalashtar would have acquired in their quest to turn the Dream of the Age? Thanks in advance.
