Halash. Hebrew for weak. Cad. Dishonorable one.
Lavellan. Rodent. Poisonous. Antidote to poison.
Trevelyian. Farmstead of Elian. Derived from... Helios. Light and sun.
Addar. Adar. Ruler. Fire.
Mix this alltogether and you got the Inquisitor, just different facets. The Human being the most noble, the Qunari being the most dominating and destructive, the Elf being the small one that hurts things but also helps them. The Dwarf being the shifty one that steps up from the results of disaster.
This is all the character we play, and the symbolism we follow. Based on the stuff I listed and other things I read. A relative nobody, though with some hints of a noble lineage or past (even for example, the House Cadash theories out there), who steps up to their ancestral power after being part of bringing damage to others, coming to ascend to rule them and divinely saving them from their enemies.
As an Israeli I speak Hebrew every day, Halash means weak, but Cad means a jug or bow.. "Ani cad le'ha" "I bow to you" "Ata halash!" "You are weak" "Wow, ha'cad ha ze mehoar" "Wow this jug is ugly"
Oh and considering some of the elven history is inspired by the jewish history, from what I understand the Nazis and antisemistics called jews "Rats", and what catches rats? Noble cats... However I am saying this from a jewish prespective... So if there were other groups of people being called "rats" as an insult please share(maybe the Romani people?)
P.S "Hadash" in hebrew means "new", "Cadosh" means holy, Cadesh means (make something holy cadesh is for male cadshi is for female)
