In our last game session, the party freed three evils that had been trapped in ice for millenia. The reason they freed them is that information was needed about how to get out a megadungeon that they are themselves trapped within. I was quite surprised that all three villians were released, as each were entombed in ice, in different chambers, beyond a chasm with no way across it that was initially guarded by a wyvern. A strong deterrent - or at least the builders of their prison, centuries ago, had thought.
The three villians, in the order they were released, were Gorrononogria (a gargantuan elder black dragon who wants to rule the world), Lady Gwendolyne (a Succubus who desires all the riches of the land) and Rendclaw (regent of the Darkened Hells and master of the thousand Soul Eaters). Even better, the heroes are now on a mission to reclaim their souls from Rendclaw, who claimed them upon being freed ('Freeing me was unwise!') by bringing the head of the ruler of the Spidercity to the demon. The elder black dragon is now who knows where, presumabley heading for the surface to submit the land to his rule and the succubus is now heading for the city of Blackport after the party mage informed her that the richest man he knew ruled that place of thieves and scum.
The campaign just started to heat up!!
