Our Hellerium metabolism is both a source of power and a weakness that can be exploited. When overcharged, it makes us burn up like dry grass. Yet the flame which burns the shortest, also burns the brightest. If we can control this process, it can give us almost supernatural abilities - at the price of agony. Thus, at the edge of death, we'll be able to inflict even greater pain on those with similar weakness, as well as on the denizens of the Shadowrealms. Only Repentia Gals, however, can withstand such self-denial.
