He said he empowered the old one, basing off of U-Do's post which has since been nullified as it contradicted previous posts. I don't know if he wants to change the empowering over to the new star, don't see any point in such an action, and would recomend having him clarify before basing anything off of it. Also, try and keep Tocarus and Tensok seperate, they have absolutely nothing to do with each other, in fact they hate each other. Tensok is a follower of Tocho, not Tocarus, and yes they are both the same being but completely different individuals, Tocho is essentially dead, his followers did not automatically transfer to Tocarus, though some may have chosen to.
Also, don't know how Umbryn would know of all this, but he has gotten facts a little muttled. Tensok and Joxander are not after Umbryn, they're after U-do. The only reason they are traveling to Umbryn is because they beleive U-do is going to try and attack him.
