that sorcerous carpet thing that Kellhus has, that's going to like shoot out 10 feet wide lasers or someting. you know it. or it will fly and Kellhus will sing "A Whole New World" with Aurang
srsly tho, airborne chariots--does that include airborne horses? because why not just ride the horses into the sky? Kellhus uses this to combat the dragon prob? if we are flying chariots around, fly some catapults us and fire straight down into Dagliash. or just hurl boulders straight down on top of the battlements.
maybe Kellhus will kill everything in the Ark, seal it, then bury it with the nearby mountain range. hell, does he even need to go into it? i guess the meta-gnosis would be good for collapsing all of the underground tunnels, then burying the thing to a point that the air inside will run out before new tunnels could be built--a calculation a Dunyain mind could make. then just hang around and check for new tunnels every once in a while--seismic-meta-gnosis
