The Rise of the Githyanki
Back in the 80's some time there was a Githyanki astral dungeon published in Dragon Magazine. It was an awesome mind-bending high-level dungeon on a floating asteroid castle with towers and rooms sprawling in every direction in an Escher-like contravention of the laws of gravity.
There's something spectacularly awesome about the Githyanki.* Thus I declare this Githynaki week, with three vaguely Githyanki-flavored dungeons for your pleasure.
Trivia: Did you know that Githyanki were created by Charles Stross for his D&D campaign?
* If you are one of those small minority of Githyanki-haters, please don't despair. Next week I'll have some dungeons with Kobolds and giant spiders in them or something.
