I've had this mutant Tyzias AU rolling around in my mind for a while so here you go. In this AU she'd be a descendant of the Signless in between him and Karkat.
Tyzias finds herself roaming between cities, perpetually just out of and too close to reach from the authorities. She wears the sign of the only possible ancestor she could have, tracking down remaining scatterings of his and the Summoner's teachings. She has no allies (unless you count the equally hard-to-find and dubiously green Stelsa- they have a sort of unspoken truce) but a decent amount of highbloods trying to track her down for hanging the teachings and history of her ancestor in public spaces...
