Black light
The light that shines down on the Bone Altar, the Black Light is the counterpart of the White Light. By reading the inscription etched into the Bone Altar one can convert to the evil Goddess of the Horde of the Summoned (HotS) Kingdom; Libila.
The Black Light is found on the Wild server and is visible as an immense beam of evil black light that shines down from the Goddess. Upon reaching the Black Light, an enormous Bone Altar will be present. The Bone Altar can be used to convert between religions/kingdoms, becoming a priest, and becoming a champion. The destruction of the Bone Altar is one of the goals in the war between Jenn-Kellon (JK) and the HotS.
If you join Libila you automatically enter the HotS kingdom, and you will become in in-game terms, a 'Blacklighter', and cannot enter the Home server. As a member of the HotS kingdom you become an enemy of the JK kingdom. Deed Guards and Tower Guards of JK will attack Blacklighters on sight, and JK players, known as ‘Whitelighters’, can attack, kill and loot Blacklighters without penalty.
Blacklighers can also kill and loot from fellow Blacklighers without penalty.
