Nycaloth

Nycademons, also known as nycaloths, are the elite cavalry in yugoloth armies, swooping down onto enemy flanks and tearing up unsuspecting troops. These arrogant, green-skinned creatures are 8' (2.4 m) tall, and possess four muscular arms, a doglike head and a pair of vast, bat-like wings. Nycaloth commanders are larger than their fellows, and lead entire battalions into war.

Notable Nycaloths
The nycaloths Aulmpiter, Gaulguth and Malimshaer led the Army of Darkness against Myth Drannor in 714 DR.
