Ramazith is a mage and the owner of Ramazith's Tower in Baldur's Gate North. Among other things, he is the mage who set green slimes on Ye Olde Inn. When the player is near his tower he will approach them and ask them to bring him the nymph Abela from house of the mage Ragefast. He needs her for spell components though he will not admit this to the player until they bring him Abela.
Ramazith asks Gorion's Ward and their party to free Abela from his rival, Ragefast, so that he may 'take care' of her.
