RuneFest Playable Beta Content
It has been confirmed by some Runefest Players that it is indeed about past bosses, and also that Nomad will be inside. (In some way)

There are also a small number of videos on sites such as YouTube showing the Dominion Tower being played at Runefest. One of these shows that Nomad, the Pest Queen and drones, the Decaying avatar, the bosses of Do No Evil, Zenevivia and the Dagannoth Mother can be fought.

 * Generous Combat XP
 * New consumable items to use on the surface world
