The four members of the group were:
- Gaurldar Ravenhand, the leader;
- Ilueth Dragonil, a wizard;
- Irlon Shulstarr, a thief; and
- Llurella Shulstarr, a thief sister of Irlon.
The Masked Marauders operated in Thay but in 1370 DR they quickly escaped from that country. After a journey through Impiltur and Calaunt, they diverted a ship to Myth Drannor, where they hoped to gain many treasures from the ruins or from other adventurers.
