Macabre door knocker

The cast macabre door knocker takes the visage of a shadow dragon, its iron tongue a handle for the magical knocking device. Raising the Tsol'teth-themed artefact knocker commands a door of light to open five seconds later, allowing its owner to enter its doorway to travel to an underground network with six exits to other Sapient locales (four if used on Meropis), similar to travelling to the clouds with Eagle's Wings. Activation and entering the door is prevented by the presence of a monolith sigil.
