Dark Matter/QnA


 * If an orgy of powerful monsters and their husbands takes place in a confined space, sealed off so their mana cannot escape, and the orgy goes on for long enough, then a dark matter will be born from the accumulating energy. However it would be rare/difficult to keep enough couples there for long enough to accomplish such a feat (many would want to leave halfway through to have sex elsewhere, or take a break to look forward to the next time they have sex).
