Thoughts about the original Exiles
After reading the legacy comics and the new Jedi vs. Sith guide, I've come to the conclusion that not only were the exiles who came to Korriban very powerful, but their ancient jedi counterparts were also very powerful. I know that the PT era is the golden age of the Jedi, but all the sources point to the ancient Jedi knowing all of these lost and misplaced techniques, such as prolonging life. Then we have the ancient teachings of one of the original exiles Xoxaan, who apparently had some kind of knowledge to help Darth Krayt continue living. So these ancients had powers that nobody other than Palpatine rediscovered. I know it's illogical to say that the originals of something "Such as the werewolves or lycans" were the best, but it seems that these ancients were at least in the force, more powerful than the majority of the future force users.
