Maandar'rik
The Marquis of the Web
This information is primarily from a PoL cherub, and should be treated as subject to confirmation.
Originally a Servant of Malthus (Earl of Death and Havoc), around 300 years ago he 'grew a spine', and decided he could do better than the 72 were managing. He created a religion and grew it slowly, staying beneath the notice of the Dukes. Appears pragmatic, and opportunistic. As the Dark Circle withdrew in 806WK, his agents took control of at least six vampires, and took power in Horsham and Mickleton in Waterford (the Hormikleton Forest vampires were neutralised.) The six vampires and a score or so of his priests were destroyed by a Guild party in Spring 806WK, freeing the two towns.
Winter 811
Maandar'rik's new form is that of a massive 60ft wide spider, a giant tarantula with dripping fangs and eight chitinous legs that support his massive body, which is bloated on devoured souls and whose faces can be seen spreading along underneath its skin.
Maandar'rik appears to have formed an alliance with the Ancient Sentient Spider that once was part of Malthus and who was a servant of the great Spider Goddess Lloyth and has become a pseudo Spider god himself with allegiances to LLoyth and Malthus.
