What is "elioud"

In the Jewish mysticism set forth in the Book of Enoch and Book of Jubilees that was carried on by groups including the religious community of Qumran that produced the Dead Sea Scrolls, the Elioud (also transliterated Eljo) are the antediluvian children of the Nephilim and are considered a part- angel hybrid race of their own. Like the Nephilim, the Elioud are exceptional in both ability and wickedness.
