Wing Cloak

A pair of ghost wings folded over the barrel - broad soft arcs with a darker line along the leading edge, as though the horse were wearing them rather than growing them.

What it can come out as

Wing Cloak, coloured	`Wcc/Wcc`
Wild type	`Wcc/n` · `n/n`

How each one is actually drawn - region by region, and the layers it is built from - is on the coding tab.

About this gene

Imported from the magic-gene intake, 2026-09-08. The source placed four wings by centre and angle. RINGS has no centre and no angle, but it does have `arc` - and a ring with an arc well under 1 is a sweep rather than a circle. Two radii give a forewing and a hindwing; a third pass at a much harder edge lands as the dark leading edge.

This one is the furthest from its source of the batch. The wings are placed by the lattice rather than by hand, so a horse gets however many the spacing puts on it - look at several before deciding it is right.

Finding one

About 1 in 893 wild horses is born showing this. That is the whole of the supply: catch one, or make one with the carrot below. Breeds set their own pools and a breed built around this gene will carry it far more often than the wild population does.

What it paints

Each outcome, described the way the gene file describes it, and then the layers that draw it in the order they are painted. The prose is the part a reader checks a bake against; the list underneath is what the engine actually did.

Wing Cloak

A ring with an arc well under 1 is not a ring at all - it is a sweep, and two of them at different radii read as a folded forewing and hindwing. A third pass draws the same sweep with a much harder edge, which lands as the dark line along the front of the wing.

the forewing, swept forward — RINGS × AXIS, painted with TOWARD
the hindwing behind it — RINGS × AXIS, painted with TOWARD
a darker line along the leading edge — RINGS × AXIS, painted with TOWARD

Wing Cloak, coloured

The same wings in a colour the line carries. Fully recessive.
