In one word, incredibly reclusive. A lone wolf with a rather neutral moral compass, Whispermaw does not interact with anyone unless it would be a plus for both parties. Very cautious and calculative, he sometimes stay silent for hours to think of how he will pursue the day before he even starts it. This however leads to him be rather "out in the clouds" so to speak. He does things that are hardly noticeable but big enough to make rather unexpected changes around him. For example, he will hunt where other packs are present and have marked the ground as territory but in a way that he is hardly noticed. However, this will make any pack that is around the area pin suspicion to not Whispermaw himself but to others packs. He avoids conflict at any cost and will judge another of his kind severely by how they speak to him initially.
But, if you get to know him, He is a very odd and funny wolf to be around. The constant zoning off and the shy glances he would make at the wolves or animals he likes it enough to tell you that he does not know how to be social at all. He will try his best to get to know you but he is also very very untrusting of others. He speaks little to no words at all but makes rather meaningful gestures. But once you have broken his shell and earned his trust, he will stick with you for the end of time.
