Rogue Trader - The Hos Dynasty
An Eldar Autarch that was relentless while stalking the Party
A primary figure in the elusive Craftworld Kaelor. He was apparently responsible for the many, many attempts at killing the Dynasty on Damaris, before meeting with the Inner Council to discuss a temporary truce. He appeared to agree to backing down from hostilities and presenting his Dire Sword to Lord-Captain Jequin Hos to seal the pact. This was yet another assassination attempt, as the sword was destroyed duing the battle with Warboss SnokGritz nearly costing the Rogue Trader his life.
The Exarch made one final push to destroy the Dynasty, summoning a massive Eldar fleet to kill the Dynasty in an attempt that utterly failed due to the surprise reinforcement from Hos Dynasty allies. The Exarch was confirmed to still be alive by Farseer Anaris, though he had fallen from favour in his Craftworld. His current status is unknown, although he did promise to return for his Dire Sword.
