Elgyem is based on accounts of Little Green Men, commonly called LGMs, hence its appearance and name.
The name might also have been taken from elegy and requiem.
If you listen carefully to it's cry, it sounds like there is a "yem" in the cry, as if it's saying part of it's name, however this does not apply to Beheeyem.
