Now I really want to try this mysterious chronomancer. I just need to find the best party for him.
Banters wise, have you any suggestions on the best NPC to gather with Walahnan ?
- I moved the quesiton to Walahnan's forum 
As for the answer... he should have more or less equal number of banters with everyone in BGEE, SoD and BG2EE Just compose a team you will enjoy leading!
Thank you. Hum, now time for some party planning then... ^^
At last found a good party to try Walahnan in EET :
In BGEE : Main char as a paladin, Jaheira, Branwen, Imoen and Kivan / Coran for Imoen dual time as a mage only.
In SoD : Jaheira, Imoen (thanks I4E), Corwin and Glint
In BG2EE : Jaheira, Anomen, Imoen, Mazzy
Eager to try the new Athkatla mod too :-)
Looks cool!
Remember, though, that Alabaster Sands were just released and there is no "EET" tag on the download page. I have no idea how would the mod behave on EET and I am afraid that the icon may end up in some really weird place! It will be adjusted in the future.
Thank you for the warning, I went for a separate install instead.
The install for BGEE is almost finished, I'm eager to gather my party. :-)
