The game gave no reference to the books or the comic series. As a self contained SW Universe type of thing, broader reference could've been made, had it been important to the story line of the game itself.
Hence, if Revan turns out to be simply a background character, they would not to have wrapped so much around him/er to pull off the new story.
I thought for sure Exar Kun (40 years previous to KOTRO1?) was referred to. I think Jolee Bindo may mention it and possibly Canderous Ordo. Not a big factor in the game though and it was provided only for background/flavor.
