Fury
From Warhammer 40k - Lexicanum
Furies are winged humanoid daemons, prefering to fly instead of walk. They are not dedicated to any Chaos god but to Chaos Undivided. They act as the vanguard and strike fast inflicting as much damage as possible in a blind frenzy.
In Greek and Roman mythology Furies were female personifications of vengeance.
