Slayeheim is a salt flat country from Wild Arms 2. It was not a salt flat, untill an ARM called the Angel Halo was activated to stop the civil war. Many of the heros and villians come from slayheim.
Also, it has been brought to Redwall online clubs, and several well know characters are from there (Maximillion, Setto, Redflash, Vincefield, Ptolomea, Cania, Antenorra, Judecca, Ard, Liz, Evans and some others)
(I hope this is the final version)
