Lucious, as expected Karnage is ok, just spotted something you have to edit. 
"with exact dates questionable due to how time flows in certain parts of the underworld, but definitely more than five hundred by mortal standard."
You could say "with people unsure how time runs in Hell" or "with this part of Hell being rumoured for having a twisted time" but in Essence we have no time-altering magic (and very strict rules for space/matter changes too).
