The Imperial Heritage Horse (called 'Imperial HH' for short) is a cross between a Friesian and a leopard breed, usually an Appaloosa or a Knabstrup, and who has at least 25% Friesian blood, and either one or two copies of the leopard Lp gene.

Breeding rules:
In Horse Isle, the only way to create an Imperial HH is by crossing a Friesian with an Appaloosa or a Knabstrup, preferably a Baroque Knabstrup. In order to ensure that Imperial Heritage Horses don't have less than 25% Friesian blood, it is not allowed to cross Imperial Heritage Horses with any breeds other than Imperial HHs or Friesians.

Conformation:
The conformation of Imperial HHs is of Baroque type (see 'Grade Baroque Horse'), and can largely be described as a blend between a Friesian and a Knabstrup, although it usually lacks the iconic upright stance of the Friesian. In general, Imperial HHs have a straight profile, small-to-medium ears, an arched high-set neck, and rounded hindquarters.

Because of the presence of the leopard gene, the manes and tails of Imperial HHs are not as full or as long as those of purebred Friesians. Therefore, in Horse Isle, Imperial HHs will be heavily penalized for having overly long or thick manes and tails. The legs are either clear from feathering or have light feathering.

Coats & Height:

Colors: bay, black, brown, chestnut, dun, cream-dilutes, pearl, silver-dapple, and champagne.
Dominant-black and mushroom don't naturally exist in this breed, but can be bred into it.
