One page dungeon contest 2012

Gavin pointed this out on his blog and I thought I'd try and enter something this year for the one page dungeon contest! My noble intentions unfortunately immediately gave way to my laziness, so the Invasion from Planet X dungeon idea I came up with has been replaced with a one page reworking of an earlier dungeon I made. So my entry this year will be The Biosphere which my Fallout players might remember as The Shining Temple.
