Take courage, players! The dungeon master has some new evil goodies for you! Here we break the notion of tradition, and stand goodness on its whining head!
Buzz! Whrr! The machinery of wickedness turns, and the gears of destruction grind at the seals of light! Before you can say "Merlin's beard!" a black portal opens, and tentacles reach out to pull you and you companions in. A most diabolical adventure commands your respect?
Roll to save vs grappling.
And read about these portals, you would-be heroes!
