Centuries ago the Stormy Mountains were a Nali fortress which has been making a stand agains Skaarj invaders. The attackers were unable to breach the Nalis' powerful defences, and created a heavy thunderstorm in the area in order to soften up the defending force before another assault attempt. After the storm raged for a few weeks, the Nali were forced to retreat, and the Skaarj could continue their conquest. The rain has now washed away all memory of that ancient war, and Liandri Corporation has now turned this area into another arena for Onslaught.
