The Threadwolf of Doorways is a threshold creature woven from shadow, velvet-dark fur, and silver thread, marked by strange keyholes set in its shoulders. It appears at places of sorrow and change, especially after mourners leave or when someone lingers at a doorway they fear to cross. Silent and watchful, it does not hunt flesh. It follows hesitation, grief, and truths left unspoken. Old bestiaries describe it as a guardian of lost thresholds, a guide that opens unseen paths for those ready to move forward. It may be approached with honesty, but never asked to stay.
