Titles the Absolute gives the characters.
I was thinking about extra titles for the characters that are not possible to obtain on a normal playthrough but which I had back then as party members.
"The Lost One who Became a Guide" Kar'niss
"The Unfailing Pathfinder" Nere (ironic title or not depending on how you choose to see it)
"The Broodmother of a Withering/Undying Circle" Kagha (it's a taunt, Shadow Druid reference, could be withering or undying based on player's choices if she had a companion quest)
"The Reject that Became Chosen" Orin (Doesn't change, because whether chosen by Bhaal or a redeemer Durge she would still be chosen if she was a possible party member)
