Blunderbuses.
Flame Cannons…
Those stone-footed, half-petrified dwarfs guarding the gunwhales would be like living, self-aiming deck guns.
gsteelwraith:
I would say the Dawi Zharr would embrace technology (or Daemon-tech), and they could build their own flying machines (minus the endrins). Flying ironclads (similar to the old ACW ships in design), and then CDs dressed in heavy protective clothing with guns, axes and hammers, and gasmasks. Building the ships won’t be so tough, coming up with figures to build an army up would be the tough part.
Zamul:
#4 for me. With Hashut dead, the Dawi Zharr dug as deep as they could to survive the endtimes, nursing their bitterness and hatred - of the greenskins for defeating Hashut, or the Duardin for thriving, of the Skaven for their tunnels and THEIR god being elevated, of Chaos for neglecting them; and most of all, of themselves.
Daemon-powered drill-trains, throw in a little warpstone and a Chaos-flavoured aether-gold from underground (why not a fluid “black” gold? 
), burning holes through the earth and popping up in volcanic eruptions for slaving runs; ziggurats standing next to underground seas of lava… The Zhaardrin Underlords! 
With Hashut gone, I’m picturing bull skulls everywhere, too. And since there would be no more mutations (or fewer) mechanical bull cyborgs to make bull-centaurs again!
And the sorcerers? Well maybe the stone ones survived, too, and now they’re nothing but fuel for the machines.
Abecedar:
Hashut dead. Nah… I’ll just carry on in denial!
Timothy Archer:
Hashut is not dead at all . Shar’tor who is a new era character can use The Mask of the Executioner ability , and the power of this mask is coming straight from hashut hands . he is hashut favorite warrior priest , hashut 's name is all over the warscroll
Abecedar:
TGFT. (thank god for that)
because who would I dedicate my Insurrection to if he was gone

I thought he had been killed by Gork and Mork. Hopefully Shar'tor means more might be coming, one day.

Wildist:
I must agree with Timothy. On the other hand, Slanesh was thought to be slain but recent rumors point it to be fighting the nightkin. For what it matters we could consider Hashut the sixth god of chaos after the horned rat, or at least that’s what I want to believe hahaha
