Tib's Talisman

The collar that Tib wears, it is socketed with a soulgem shard on the back given to him by his master. The shard is from his own soul and having it is the only thing keeping him from becoming a mindless undead drone. He is free to take the collar off if he desires, but he fears that if he does his mind will cease to exist, for this reason he himself put a lock on the collar so that it wouldn't be so easily removed.
