Didn't Baal eat children?
That was Molech. Children were sacrificed to Molech by being thrown alive into a sacrificial fire (Jeremiah 33:35).
The Hebrew word for death/the underworld was Sheol, so Sheolech or Sheolek might work.
A Hebrew-English dictionary might be helpful. There are several online. I turned up the following for "deadly" at
http://www.eliyah.com/lexicon.html akzar ak-zawr' from an unused root (apparently meaning to act harshly); violent; by implication deadly; also (in a good sense) brave:--cruel, fierce.
harag haw-rag' a primitive root; to smite with deadly intent:--destroy, out of hand, kill, murder(-er), put to (death), make (slaughter), slay(-er), X surely.
chalal khaw-lawl' from pierced (especially to death); figuratively, polluted:--kill, profane, slain (man), X slew, (deadly) wounded.
And for "infant," I got:
uwl ool a babe:--sucking child, infant.
owlel o-lale' or lolal {o-lawl'}; from 5763; a suckling:--babe, (young) child, infant, little one.
So....Azkarul, Haragul, Ulchalal...?
