The yeti from Wintral has hooves
and generally, I always come up with units based on stories, I imagine how the unit/race lives, and from that, the units are born. For example, there was also a fish-man slave that I didn't finish. He was supposed to work on the rice fields of the cultists - even though the cultists are medieval Europeans, they eat rice and drink rice schnapps like in the New Camp.

but sometimes units appear where the visual image is more important than the story - for example, there was an idea about cursed paladins guarding an artifact of angels that was defiled by demons. They were supposed to contain the corruption by completing quests for witches, but both units from the Chaos faction moved into the category of barbarian worshippers of Askh. As a result, the knight became undead, and the witch casts vampirism and teleports in a bloody vortex. The images of a woman with a deer skull on her head and a gloomy knight with a two-handed sword were important.
