As was often the case, Callum's paws were taking him around the outside of Casa's borders, his head lowered, nose scenting the ground. He was not hunting, but tracking scents as they crossed the zone of land where the scents of Casa's members were strong. Rabbits and deer did not care so much about the markings as to prevent them from crossing freely, and he did not care if they did besides to report to his fellow Cavaliers and to make use of the information himself when he was hunting.
Similarly, even the children were growing big enough to leave the pack's borders alone as long as they did not go too far, and the other members' movements in and out of the pack lands were not his business to comment upon, unless something happened. However, if he had come across instances of trespassing by others, Callum would have felt it necessary to track down the offenders and remind them that they were to respect the scent marks.
So far, Callum had found nothing but for a couple places where those who had approached Casa had been greeted and accepted into the pack or, apparently, their questions answered and they turned away. Nothing suspicious and nothing exciting. So when Iorek howled, it was a welcome distraction. Callum's head came up and he loosed a short howl in return, to let Luca or Lyris know that he was going to answer, and to let the potential joiner know that someone had heard him and was inbound.
His secui stride ate up the distance even at a lope, and the mostly-white wolfdog was soon standing in front of a familiar face. His pumpkin eyes scanned the brown and white male he had encountered while hunting several days before, noting that he looked no better fed than he had when Callum first met him, though otherwise unharmed. He stood in his Optime form, a pair of cats flanking him. Tail waving in the air and his tongue lolled slightly out, Callum greeted him with, Iorek, wasn't it? Who are your friends? What brings you to Casa di Cavalieri?
