Spirit Reservoir Owners

Spirit Reservoir Owners are an extremely small group capable of incredible feats. First and foremost, they are essentially immortal: even if their bodies are destroyed, they will simply reform, though the speed of the revival varies. In addition, owners all seem to possess near god-like power reserves. However, these gifts sometimes come with a high price: in at least two cases, an owner's longevity seems to be tied directly to an ability or need to drain the lives of others.
