This is a drawing of how I picture the Linyaari species to look.

Linyaari are a race of humanoid unicorn people created by Anne McCaffrey in her Acorna series. Throughout the series, its learned that they are a genetically modified species made from a cross of unicorn and a shifter species of Anne's creation.

They have a horn that has the ability to heal wounds and purify toxins in air and liquid. They have three fingers and a thumb on their hand though they lack the final joint on their fingers. their legs end in hooves. Colorwise, they come in any color or pattern horses come in with one special coloration that is illustrated by Riin here. Its called StarClad, where the color leeches from them as they travel through space leaving them pale with silvery hair.
