It can be considered variant of Achilles or Achilles, which is a male name of Greek origin and means protector. It is also an inflection of aquilar which means uncomfortable, annoying, disturbing, disturbing.
I never saw it, and if it's not a poetic way to summon the storm black clouds, I can assume it's a mistake by achilles, rents, achilles (aquilatar), eagle, annihilate (annihilate), make (maquilar), , . . .
