Accepting the cloth with a grunt, Ris-Janna spreads it as far as it will open across the pocket of active magic, then picks a coin out of her pouch as the rest climb inside. Holding it into the cranny, she passes her other hand over the coin, plunging the pocket into shadows briefly until she pulls the coin back into the dead-magic zone and passes it to Xuuvosic. "There. Cover the coin. You end up in a group of hostiles... you uncover it and teleport again."
With that, she squeezes into the pit herself as well.
