Gargoyles tend to be lone hunters, though sometimes they band into fearsome tribes called "wings" for protection or sport. On rare occasions, wings become relatively stable communities, and gargoyles in wings may even ally with other creatures such as demons and intelligent aberrations, though these alliances exist on a razor's edge. The majority of gargoyles are treacherous, vindictive, and petty-traits that preclude lasting partnerships. Many tend to be obsessive and compulsive. Some are collectors, focusing on anything from books to grim trophies, while others are ritualistic or overly passionate about niche intellectual subjects or certain artistic motifs. These tendencies often contribute to the dissolution of wings as individuals' obsessions and compulsions clash.
