It wasn't just outside the outpost of Lion's Heart that was undergoing combat, but the inside as well. All around, people were dying on both ends, but the sad fact of the matter was that Nightfall had more members. The fighting members of the Lion's Heart faction only came out to 500 strong members. The members were intersexual, meaning a mixture of women and men alike.
However, Nightfall had double their numbers, coming out to 1,000 strong members. All of which were male, all of which were just as disgusting and cruel as their leaders. They did not fear death because they saw no reason to. They lived their lives the way they wanted; in a sense, they were like a Mercenary faction, but the numbers they totaled back at the home base said otherwise.
