Jax

Jax was the Ghost of the Praxic Order Warlock Eriana-3. He helped Eriana-3 assemble the fireteam sent to kill Crota after the Great Disaster.

In the Hive tunnels, Jax warned Eriana-3 that something was draining his partner's Light. In The Stills, Eriana-3 ordered him back to the surface with a recorded message, and before leaving he recorded her confrontation with Ir Yût and erased the Deathsong from the recording. His final line was "If anyone is listening… don't trust Toland." Jax is presumed killed by Ir Yût's Deathsong, and a Guardian later recovered his remains and final logs in the Circle of Bones.

Jax is first mentioned in Destiny: The Dark Below and again in The Taken King, and first appears in Shadowkeep.
