Gham Banni is a venture-captain in the Pathfinder Society operating out of Osirion. Of the many Pathfinders reporting to him, the most notable is perhaps Channa Ti, the half-elf druid who sought the lost city of Xanchara in 4709 AR. He is known for using a soft green papyrus and magical signet ring to sign his correspondences.
