Djinn

Beings with strong elemental magic affinity. Appear to be classified based on said elemental affinity. Djinni are descendants of gods who became mortal, so the general rules of biology are somewhat vague when applied to them. In addition, Djinni-human hybrids tend to be stronger than pureblood Djinni after their awakening.

Sorcery is kind of the best counter against Djinni.

Awakening
It's speculated that those that possess djinni blood can awaken their latent power under the right circumstances. The awakening causes a radical change in the aura of the affected person, which is without a doubt a very traumatic experience. Ch. 68

Fire Djinni
Fire Djinni are notoriously vindictive and easy to anger. Ch. 68 The awakening of fire Djnni heritage is the most dangerous. Ch. 69

Wind Djinni
Wind djinni are indeed whimsical and rather promiscuous... but Yassen would take mild offense if told that he's a womanizer because of his heritage.
