By those accounts, then by the gods, you're right! Allison should rule all of SA again.
Anyway, while I make the occaisional observation or joke here, don't expect the IG stuff to be effected by anything on the forums here. From a relative newcomer to Dwilight, yes, Sevastion appears to be a rebel. It appears that Solaria is no more, and he up and left the current contender for the title of the Lurian empire in a huff.
Whilst I don't expect it to really translate fluently to IG (not without the normal amount of backstabbing and whining anyway), what would Swordfell's view on a Lurian Empire be? Would they consider it illegitimate in a historical context?
