Border is a rare marking modifier that adds an outline around another marking. The markings that Border can modify are any markings that do not only have a gradient edge. Border can modify up to 2 markings. In dominant form, you can have Border modify as many markings as you would like. If there are no markings for Border to modify, then Border will create a line right down the mid line of the dracovix starting from their throat and ending at their tail.

Whatever marking that Border is modifying, it can use a hard, soft, mottled, or textured edge, unless the marking has a gradient edge, which Border cannot modify.

Border will fade into the background alongside whatever marking it is modifying that is also fading into its background.
