The roster for the Titans over on CoMUX

-Wonder Girl (Cassie Sandsmark)
-Zachary Zatara
-Zatanna Zatara
-Wiccan
-Flash (Wally West)
-Changeling
-Vorpal (my Original Character)
-Bunker
-Raven
-Oracle

So far, Vorpal is the only Original Character to join the Titans in game.

The tower appears to be vanishing due to the fact that, in-game, the Tower was destroyed in an assault by Amanda Waller. For a time, Wiccan 'borrowed' a version of the tower that existed in another reality... but unfortunately it caused fractures in reality through which other realities were seeping through, making things rather -weird-, so eventually he had to take the tower down.
