Two further notes:
In spite of the code saying "DarkAvatar" at some point or another, this is a Twilight of the Arnor map, if you run it in DarkAvatar, the game will crash (DA does not support ascension starbases nor immense mapsizes).
In order to play the map, click on Kosh's link and copy the code to notepad. Then save it as SoulCrushing_01.GC2Map in the Data/custommaps subfolder of your Twilight of the Arnor folder.
I didn't actually get to play it yet though.
