Hethrir
Hethrir is an existing character from Legends.[1]
After Palpatine returned to life as a clone eight months after the Battle of Endor, Hethrir pledged his allegiance to him again and used his slave ships to ferry slaves to Byss. In 5 ABY, Mammon Hoole smuggled the severed and preserved head of Triclops onto one of those slave transports, hoping the gift would placate Palpatine over Hoole's failure to deliver Ken.
Hethrir also remained nominally aligned with the Inquisitorius, retaining the loyalty of the Inquisitors Antinnis Tremayne and Loam Redge.
When Palpatine used the Kaan Heptad to submit every darksider in the galaxy to his will near the end of 5 ABY, Hethrir felt his mental touch while inspecting slaves aboard his worldcraft, the Rebirth.[2] Soon after, Hethrir felt Palpatine's clone die. Freed from the Emperor's compulsion, Hethrir announced to his servants and slaves that the old Empire was dead and could now truly be reborn.[3]
