Well, I think I got everything I wanted from the Taldan arc. See drow, check, kill drow, check, get a drow contact, check. Went on to ruin House Basri into non-aggression (still want to find out what the repercussions for them will be); got to know some powerful people to our mutual benefit (still want to get those diplomatic credentials, but more as a way to extend our service to people we wouldn't mind working for); got to stick it to the Aspis and demon worshippers again.
Now all I need is to establish a basic roadmap for the events-to-come (not sure how long it'll take to get Sirim's body back, but I assume it's not going to happen before we leave; also, there is the Jernashal expedition we'd need to be back for in some time), and to pester Bjorn into finding out more about Ulfen kings and Gavis' father... and I will be ready to depart.
That we didn't catch up with the Azlanti survivors is a pity, but we will likely pursue the matter at a later date.
9/10, would visit Taldor again.
