Shadecinder

Shadesclaw is the secondborn daughter of the Shadefolk lineage's matriarch, Shademouth.
She is fiercely dedicated to the cause; spreading the Shade's influence from the inside of other Clans like a blight until they trust her enough to receive a gift; a shred of real newly created Shade that can grow within her. Notably, this gift can only be passed down to her children-- any children with the same blackened markings and the same wing pattern have a stronger lineage than any others who don't.

Any offspring of Shadesclaw who have Obsidian Savannah primary and (any colour) Noxtide secondary are strongly Shadefolk lineaged regardless of tertiary colour or gene. The only absolute requirement of the Shadefolk Lineage is to have Obsidian Savannah; if they don't, Shadesclaw's influence is too weak on the hatchling to have successfully passed on the fragment of Shade.
