Of course nobody reads this forum anymore but I just had a new Myth story idea for the first time and ages and don't want it lost to history...
Something got me to thinking of old discussions about the Leveller and what exactly its name means, "leveling" as in demolishing, or "leveling" as in making even or balanced.
It strikes me: what if it's both, as seen from the perspective of different races in the Myth world? From the perspective of whoever the dominant powers are, it's just something coming in to destroy all that they have built. But from the perspective of everyone living on the outskirts of those mighty civilizations, it's a force of equalization, knocking down the great powers and in doing so giving them on the fringes a chance.
Which could be precisely how the Leveller entices any living beings like Ghols into its service: they don't want to live in a world of the dead, but they hate the Dwarves and feel oppressed by them and will happily work with whoever would stamp them out. Maybe likewise the Myrkridia, and the Orcs who I think became the fir'Bolg and bre'Unor (after some, the former, turned away from the Leveller, and some, the latter, remained in his service, under the name b'Y'laggo -- I've talked about that theory somewhere in recent decades haven't I?). Basically the same kind of thing that entices real humans into terrorism: the powers of the world are rigged against you, so fuckin' destroy 'em all.
It would fit with themes Bungie had already established, as in with Thoth from Marathon siding with the Pfhor as soon as Durandal and the S'pht got the upper hand.
Perhaps this is even the way that former great heroes are turned and possessed by the Leveller spirit. The empires they built become stagnant and oppressive, and with age and wisdom (as they would see it) they realize that what they did in their youth, out of good intent as it may have been, was in the end an evil, and now must be undone.
