Lilith was introduced in February of 2010 as a vampire elder and part of a special event. The player must collect a certain number of white lilies to complete her mission. The reward for completing her mission is the rare ability "Kiss of Death." This ability comes in three levels: standard, superior, and epic. Each level of the ability is given upon a certain percentage mastery.
The elder Lilith is most likely inspired by the story of Jewish lore. Lilith appears as a night demon in Jewish lore and as a screech owl in the King James Version of the Bible. In later folklore, "Lilith" is the name for Adam's first wife. She is almost always presented as a demon or the personification of "the evil woman."
