We Need to Defeat the Endbringer

I told Tara about the vision I just had about the final moments of my father's life just before the Endbringer took him. I know that I'm the Endbringer's next target. It nearly ended my life two times now. It will keep coming for me until it finally does what it did to my father to me. I told Tara that we need to put an end to that dimensional abomination of horror once and for all, and we need to do it before I become its next victim. I have no idea how we can stop such a horrible abomination. However, we'll most likely need what's inside that dark dimensional tower to help us.
