Darth Tumulus, covered in shadow.
Darth Tumulus was a male Sith Apprentice in 129 ABY. He was one of ten apprentices trained by Darth Echo for his new Sith Order. His favored Force power was Force Scream, yet like his other apprentices, he was trained into immortality by Echo when he learned Force Phoenix.
Behind the scenes[]
The word "Tumulus" is Latin for "Grave", which is what Darth Tumulus wants to put his enemies, in fact the entire galaxy, inside of.
