Shuggaroth

One of the Elder Gods of the Outer Void, Shuggaroth (SHUG-ah-ROTH) is often called the Blood God by his mortal followers. The cult of Shuggaroth serves him in exchange for power and attempt to bring Shuggaroth, who they call the Cosmic Leech, into contact with the world, so he can drain it of life and light. His cultists believe that they will abandon the world as he feasts and ride the Cosmic Leech into eternity.

The Cult of Shuggaroth
The cult of Shuggaroth puts emphasis on power and hedonism - the world is doomed, and will ultimately be drained by the Cosmic Leech and left as a dried husk, so the cultists aim to enjoy it while it still exists. Their other focus is on power, and this cult is often found operating in the highest echelons of society, pulling strings to hasten the arrival of Shuggaroth.

Vampires
Many of Shuggaroth's worshipers earn and accept the Gift of the Blood God. This grants them increased strength and speed, supernatural senses, and near-immortality, but comes at a cost. This cost comes in the form of the Hunger, which can only be sated by the blood of sentient creatures. Almost all vampires are part of the Cult of Shuggaroth, and even those who go rogue can find themselves subject to his whims.

Sanguine Lords
The Cult of Shuggaroth's answer to a traditional priesthood, the Sanguine Lords are vampiric followers of Shuggaroth who have been imbued with even more power by their Master. The Sanguine Lords answer to nobody but Shuggaroth, and they pursue his goals with single-minded obsession, spending far less time wallowing in hedonism than the rank and file cultists.
