His growing fame had a bad effect on Marim. He became pompous and arrogant and prone to throwing a tantrum if he didn't get his way. However, he was very competent, knowing nearly every song from every culture across Faerûn.
Marim was an entertainer and musician in Mulmaster, together with his band. In 1491 DR, the Blades of the city competed with each other over the arts, and Marim became a top pawn in their proxy war, gaining great fame. One day, he was invited to play at a party hosted by Zor Faltyn Gos.
