Welcome!
Right..in order to get Keldorn...which is my fav party person, you must under take a huge quest in the temple district.
The quest is relatively hard so make sure you are good! I did it in chapter 2 but not fully....I won't spoil you!
Go to temple district and speak to the Helm Priest.
Go into the sewers and he is in the west side.
Hope that helps....
