Something along those lines

He was silently pleased when the girl fell into step with him and began to follow his lead, though he could tell that she was still fairly new to the task. His dark head nodded once when she confirmed that Cairo had not come to that lesson yet. Drachen would never knock someone down though for putting in effort. "The pleasure is mine, Audra." he rumbled, his blue eyes taking a moment from scanning to look at her honey brown eyes before returning to his task. He took several more strides and pauses to listen before he answered the younger wolf's question. "I do, it is one task that is shared amongst all the ranks here in Valhalla." Though now with winter settling in and the threat of a raid coming with it, Drachen planned on walking the border more often. The male fell silent once more, the sound of his pawn crunching on the frosty ground was almost undetectable. Hunting and patrolling the border was only half of his duties to the pack but only he and the highest ranks knew that.

"Basically you are looking and smelling for anything unusual or out of place, like a strangers scent that keep returning or walks along the entire border. Also look to see if a scent has traveled inside the border. Respectful loners or rogues will acknowledge the scent and visual markers and turn back several strides before they even arrive at the actual border, give or take depending on the direction of the wind." He explained, his voice never rising above a calm, quiet speech. He glanced his oceanic blue eyes to Audra, taking in her expression to see if she grasp what he was saying before he abruptly stop and his nostrils flared. His dark face turned towards the lands beyond Valhalla and his eyes scanned the terrain. "What do you sense?" he asked the girl. There was a loner's scent in the air, fresh, but only in one small area as if the wolf noticed the border then turned and went back the way it had come. It wasn't something Drachen would have considered investigating further besides maybe urinating on the loner's scent if he had been a rather bad mood, but it certainly was a good gauge to see how well the girl used her senses.
