We meet Set Harth in the final book of the Bane trilogy and and the end he steals Darth Andeddu's holocron and it's implied that he will eventually learn the secret to eternal life. I'm just wondering does he show up anywhere else in the lore? He seems like he'd be a fun character to follow and learn more about it. You could write some fun stories from his perspective. I'd be really interested to know if he survives up until he Rise of the Empire era. Maybe he finally regretted not becoming Zannha's apprentice. Anyway, does he show up in any other books or comics? I think his story would be well suited to a comic series format.

Personally I would like it if Set Harth didn't learn the secret to eternal life, is kind of a sweet irony that immortality, the thing all Sith strive for, is the one thing they will never achieve
