Tao
What if Tao were summoned by Galanna to complete some sort of holy quest to appease the other gods? The catch would be that Tao would have to go it alone because only one mortal Galanna chose would be granted safe passage into a dangerous, forbidden area of the multiverse, and a mortal just happens to be needed to complete the quest. As for what that quest is, perhaps something related to the Defenders' quest, so it would be kind of like Tao is still helping out. Just a suggestion, have to split, laters.
