They are carnivorous horses bred long ago by the Jaghut, and stand twice as large as regular horses. Current populations can be found on the Jhag Odhan of the Seven Cities subcontinent and kept by the Teblor in northern Genebackis. They seem to have a genetically inherent attraction to blood-oil.

'The horses came in their hundreds. Grey as iron, larger even than those Karsa’s tribe had bred. Streaming, tossing manes of black. Stallions, flinging their heads back and bucking to clear a space around them. Broad-backed mares, foals racing at their flanks.'

HoC, UK Trade, p.515

'From my blood came their longevity. The Jhag horses breed infrequently, insufficient to increase, or even maintain, their numbers, were they not so long-lived...They are being hunted to extinction here on the Jhag Odhan...By distant kin of yours, Thelomen Toblakai. Trell.’

'The Teblor – my own people, who dwell in the mountains of north Genabackis – maintain herds of what must be Jhag horses.'

Havok the Younger

'another stallion, this one just entering adulthood... A mane and tail of white, not black. Long-limbed, muscles rippling beneath its sleek hide. Grey eyes.'

HoC, UK Trade, p.516

'You shall have to wait for your meal, Havok. This one still lives.'

Karsa to Havok of Samar Dev

'Not quite a horse either. Tall, lean and pallid, silver mane and tail, with eyes as red as blood.'

The Second Seguleh's Horse

'The Second drove his long-dead Jaghut stallion into that dying portal-'

TtH UK Tpb, p.883

'At that instant the rider's Jaghut horse collided chest to chest with a third hound. Bones shattered... the Hound - which seemed stunned, as the undead horse stumbled back.'
