Not really just Old Republic takes place alot further ahead in the time line, there is an entire religion dedicated to him lol, and tbh they didnt need to bring him back for TOR at all since it was so far ahead but they did a thing and he plays a part, will leave it as that to avoid too many spoilers.
Think it was done more so The Old Republic could use the universe of KOTOR without interfering with Revans tale so much in case they can ever continue his and the exiles stories. Which I think is better cause then one day if we are lucky we will get a KOTOR III and still enjoy similar game play and story in TOR
You see/feel the effects from his era though in the game.
Sorry for the late reply, I dont check my DA as often as I should.
Parts of it yes parts of it no, the armor and mask are originally parts of commission I had done years ago, but have had many mods done to them over the years so they are currently about 70% original and 30% my mods. The fabric is all done by me.
I am also making this cosplay from the ground up currently that will be 100% made by myself for a different look for a more post Sith Lords like Revan.
