The Bloodcursed, a group of mostly naga, are found on the Bloodcursed Reef of Wyrmscar Island and on Bloodcurse Isle, both part of Bloodmyst Isle. They have taken over several ancient night elven ruins in Azuremyst Isle and Bloodmyst Isle.
These naga have released a foul taint that keeps creatures from truly dying on the two islands east of Bloodmyst proper. This clan of naga is ruled by Atoph the Bloodcursed, who defends the statue of Azshara on Bloodcurse Isle.
The bloodcursed naga might be Wrathscale before they were cursed.
