The drow goddess of disease, decay and poison is a very ambitious goddess and her plans are nothing short of becoming the head of the drow pantheon and rising to greater goddess status. She makes her home in the abbyss. The palace is in an advanced decay state and all manner of her favorite pets are present: spiders, snakes, poisonous toads, rot grubs, rust monsters, dark weavers, retrievers and other such hideous creatures.

Like the other drow gods she wants the drow to become the masters of the underdark and so she helps them by sending her avatars, secretly of course, to spread diseases, to poison their enemies and to bring her decaying touch to their cities and homes. She doesn't send omens to her priests but will send them prophetic dreams if a powerful enemy approaches a state where he must be weakened fast or to do other such shadowy plans.

Duties of the Priesthood
They must spread diseases, decay, poisons and other weaknesses in the lines of their enemies and of the enemies of the drow race (namely the surface elves) so that the drow could prosper and grow. Note that this is a very violent priesthood and the priests will use whatever means available to destroy and weaken their enemies (PCs beware!) and will do so in the most cruel way they can find and use to make an example of that enemy.

Priests of Ma'azbert walk around clothed from head to toe, with masks and a heavy scent of incense to hide their hideous look and smell due to
the diseased wounds they have on their skins (Ma'azbert's gift) but are unaffected by. These wounds also reduce their Charisma by 1 point for
every level they advance till it reaches Charisma score of 1.
