Well, okay, I think I misread some of your characters. About the rift in general. Remember that sword Flax had sent to Odin? Its still knocking around and, if the group does go to Tarsis Vidar will need that sword. Mainly because by that point Aesirean weapons will be worth about a much a chocolate swords.
You remember that light that eminated from Hal's sword? Well thats going to be happening more and very shortly its going to start doing some very interesting things to those Sith.
So basically Hal will say:
"My father was going to give this to his friend and ally, what should I do with it?"
