soul eater

[polli]

Just starting playing and i love the game but who are these soul eaters who start on the island of rahala as I can't find any info/ history about them

Between heaven and hell lies an empty void, a place where those who came before man exist. Creatures outcast from the grace of ancient kings have looked deep into the minds of the weak and exploited the desires of the ravenous. Soul eaters have come to plague these troubled times offering dark knowledge in return for chaos.

That's it think. You might be able to find other references in the unit descriptions of the other rebel factions. They're a mystery even to me..
