Moonbase Alpha
From FenWiki
Moonbase Alpha, found near Luna's North Pole, is a more hardtech approach to a city than is usual in Fenspace, consisting of connected housing modules buried under the regolith.
The city is considered more of an industrial centre than a place to live in, despite being almost completely self-sufficient. However, Manny O'Kelly's Bar and Grill (on D Level of Alpha) is one of the best-regarded eateries on Luna amongst those who can afford the price of non-vat-grown meat in Fenspace.
