Played it for 8 turns. Got the Khazad on their back foot.
You've got mages and adepts sleeping in the boonies of your territory. I woke them up and sent them to the front line. I handed out law 2 and fire 2 to those who could get it.
First order of business was killing the amurite counterattack stack. There's one a bit SE of Ciriail that can put out about 20 fireballs a turn, which will fry you if you let it be. I lost a couple of your ultravamps killing it, but I couldn't afford to give it a single turn. The khazad army I let simply advance of udenarat and take it. (they also reinforced with ~80 slingers.) It had like 10 of your longbowmen (really well set up btw) which got a lot of kills, and left a bunch more khazad stranded and hurt a tile away from the city. The khazad army moved on towards cevedes despite its injuries.
Every turn, I sent fireballs, then the strongest vamps, then valin and losha, finally followed by weaker vamps, confessors and such at the main khazad army. By keeping this army regenerated and with medics constantly, and by having them end turns in cities, I made sure they never had to stop to heal. They kept taking udenarat, I kept taking it back with longbowmen (the unit I made the most of in your high production cities.) Every time they retook udenarat it left them with wounded stragglers which were picked off by Einherjar, which then drew attacks by surviving an extra turn, leaving even more hurt stragglers, etc etc. The main army made it to cevedes, smashed the garrison, then... stalled out. By the time they were on the move again I killed all but like 10 of their champions, and the stack turned tail and headed toward home.
This is def. winnable. I lost I think 5 really strong vamps but made some replacements, Valin is now a terrifying beast, and the khazad offensive failed at everything but griefing 2 of the old amurite cities.
Protips:
Governor's manors are #1 priority in all cites. I noticed some of your cities didn't have them.
Public baths are higher priority too.
Use mobility more often. That + haste lets your guys attack pretty far, then retreat to the safety/increased healing of a city in the same turn.
Upload your damn saves to CFC instead of putting them on personal webspace in




ing 7z format. If you don't know how, the attachment manager is here:
And from there it's easy enough to figure.
