Brilliant! That's the exact sort of daisy chain I wish the prologue could accomplish. It just feels very in the spirit of Dungeons and Dragons. Sure it's a bit or work, but that work pans out down the line and makes the whole custom angle to feel much more fully realized.
Ps. Also in fairness to the spirit of the OP's question... if I had to pick it's still Lae'zel for me. In the event that there is more insight into Gith culture on offer there or whatever. I'd probably try it once just to see what it's about. Though I still wish they'd focus on TAV - ATTN Charname.
That's more why I'm here.
I also enjoyed the DAO approach, and the NWN2 approach to this stuff.
