Vote! Other options welcome, but they should probably include a reference to HGTTG, DotA, Kansas, Monty Python, or a word that just sounds cool.
For those of you that don't know what Lamuella is:
Lamuella is the planet on which Arthur Dent lives and works as The Sandwich Maker at the start of Mostly Harmless. The planet is mostly made up of villages, but intersects a plural zone, allowing for teleportation to the Domain of the King. The primary species of the planet are humanoids, Perfectly Normal Beasts and pikka birds. The residents of Lamuella worship a deity by the name of Almighty Bob.
To Arthur (hgttg reference), its as close to Paradise as he can find.
The other references:
War-Room - should be fairly obvious, fits the unTactical name better than the others imo even if its not catchy
Land of Oz - I'm closer to Oz than any other clan member and have been on the yellow brick road :O
chasm - no idea, sounded good though
