Strodhäs

"Two dark blurs sprung up from the ground behind the trembling host of soldiers, arcing over them and landing with a hefty splash of mud. Rising up from the soggy earth were two black horses that rested upon not four but eight legs each." "—The Sword and Its Servant"

Strodhäs were eight-legged horses used by the Löwa in battle.

Physiology
Strodhäs were black in color and had oddly elongated bodies to accommodate their extra limbs. They could run very quickly and agilely, even through heavy mud and could leap tremendous distances.

They were powerful enough to pull wagonloads over fifteen times their own bodyweight.

History
Strodhäs were once the steeds of Mannkind that were then adopted by the Löwa as a means to defame their image (and one would assume, for the strodhäs' utility).
