The Militant Myrlochar, also known as the Order of Soul Spiders, is an
elite military order composed solely of male crusaders and found in the
few dark eleven cities where Lolth is revered and males are permitted to
enter her priesthood. The Militant Myrlochar directly serve the ruling
Matron Mothers of the city in which they are based as agents of
uncontrolled destruction, tirelessly hunting any creature designated as
their quarry or who interferes with their pursuit and wreaking havoc
until recalled (which rarely happens) or destroyed (their most common
fate).
To learn more information about this order, try to meet and speak ICly with
