Long tendrils of membrane trail off of wings or fins, like tails on butterfly wings.

Pennant may appear randomly in breeding, or may be passed down from a parent which has it. You may freely draw custom lines for it, and please check the bottom of the page for pointers and ranges!

Markings can appear on Pennant, especially where they overlap. Pennant's Extra layer may be ignored or may be any Natural or Base family color. 

When drawing your own Pennant, you may make them about half as thin or twice as thick as the official lines. You may add up to three pennants to each 'section' of the trailing edge of the wing (space between fingers) or individual fins, with a minimum of one pennant.
They may have curved shapes, may twist or curl, and may appear in front of other wings. Pennant may have a varied edge, with a rough or wavy shape.
Pennant may cover the wing claws! The keratin does not have to show in this case.
