" The only creature able to evade death temporarily is the elusive phoenix. Although this particular being lives a natural life span, it cannot be killed through unnatural means. Any attempts to destroy it will only result in the phoenix rebirthing in fire. While able to produce progeny, it should be noted that the magicks of a phoenix are unique. There can only ever be one phoenix in existence at any one time. "
