The first book is a really cool rise to power story. Bane's growth from a miner to the Dark Lord of the Sith was enthralling imo, and pretty satisfying to read. Its also really interesting learning about how Sith are trained and how they operate outside of blowing up planets and zapping people in the face, as well as how people actually end up fighting for the Sith despite them being insane supervillains.
Anyway, my point stands. Take out the graves and Zannah would have won fairly early on.
