A figure of Assyrian origins who is portrayed as an eagle-like god of agriculture. In Christian lore, he was regarded as a fallen Principality who became Hell's master of cuisine.
"A fallen angel who is Beelzebub`s personal chief of cuisine. He has authority over temptation through delicacies and food. Before he fell, he was a principality that guarded the Tree of Life in the Garden of Eden. He is said to have been worshiped by Sennacherib, king of Assyria. But because tens of thousands of Sennacherib`s followers were slaughtered overnight by an angel of God, Nisroc forsook God. He then rebelled alongside Lucifer and was cast down. After becoming chief of cuisine of the lords of Hell, he is said to cook dishes with the fruits of the Tree of Life to this day."
