I’m a madman and am not a huge fan of seeing my lord charge around on a Bale Taurus. It just seems wrong for guys living underground or in barren hellscapes.
I’m looking for a mount that’s a bit more…Balrog-y. Or at least more keeping with mining, mountains, heat, etc
Chaos Dwarfs build citties with Ziggurats so they not always live underground. Miners were using horses undeground so a Taurus living undergound does not feel that bad.
Mechanical constructs fit the theme very well, either as purely Dawi Zharr-made machines or as bound daemons. Bonus points for constructs that resemble monstrous creatures. Combining any of these ideas with mining machines, planquins, or over-the-top chariots, etc fits within the army really well also!
Some kind of mechanical crane rig with arms for grabbing with dual mounted gyrocopters on the back and a ridiculously exposed sorcerer on top piloting the rig!!?? lol
An easy version of that would be Brokk Grungsson from AoS. Big flying balloon with a cannon and chainswords. He needs a proper beard and hat though - his are just plain ordinary steampunk. Something with propellers would look better though.
Maybe a smaller magma dragon, with a spiky iron collar around it’s neck might be suitable?
There is of course the Lammasu which while somewhat bovine is often modelled with frontal claws or full claws rather than hooves.
You could potentially do some kind of hellforged mining machine - think a big K’daai construct designed to bore through the rock - the ‘flying’ is represented by the fact that it tunnels under terrain rather than flying over.
Or if you want it more fleshy - perhaps some kind of serpentibe tunnelling worm - though you might want to figure out a solution re how the guy on top fits though the tunnel as it goes, without being shaken off in the process (might need a special howdah with frontal protection for that).
If you want your mount to look like a Balrog, then use a Balrog. That’s what I did, because I’m not too keen on the idea of a flying bull either. Otherwise, I have dragons in my range and I’m currently painting Archaon’s demonic mount. In my opinion, this suits a Dawi Zharr much better anyway!
