The folks at Curse were able to conduct an interview with Mythic's Cal Crowner and Josh Drescher about the soon-to-be-released Ultima Online: Stygian Abyss expansion pack.
Curse: New dungeons have always been exciting and some of the past additions, Lamp Post stealing in Doom, the Dark Father, etc. What's in store for players with Stygian Abyss?
Cal: The Abyss. If you've seen the trailers you'll know that the Abyss is MASSIVE. The idea is the Abyss is out of time, it's in a void, and the areas don't make sense. There's one area called the "Silver Sapling" and there's this massive glowing tree in this area next to lava pits and you'll notice in different areas you'll have a different experience. If you enter the Abyss form Britannia you'll have a very different experience than if you enter it from the Gargoyle side. Everything comes together in the Chamber of Virtue where the Slasher of Veils is and there's a chasm in between that divides the area. Within the Abyss there's between 7-10 smaller encounter areas and will really give the players a unique experience.
