So, Ellie's from a world where everyone kind of naturally emanates magic, and is trained specifically in picking up emanations of darkness-based magic in particular. So, with that in mind, I would like to present... A permissions post! Since the rules of magic obviously differ from world to world, I'll add a few key clarifications here:
1: All magic she detects is mostly in terms of the six elements of Fire, Water, Earth, Wind, Light, and Darkness.
2: Unless you're inherently magical, it's doubtful you're emanating magic all the time, so this likely only picks up active casting or something that has an active spell working on it.
Another key point is that this isn't active magical sense, but passive, so most forms of magic concealment will probably still work.
Just don't try the concealment method of "hide the dark magic by burying it in dark magic", that never works.
Ahem. Anyways, the point is: Is your character inherently magical, and would she pick it up?
Is your character magical?: Y/N
What is their primary element?:
Do they have any form of magical concealment?: Y/N
Anything beyond this can basically be determined based on the situation, I think.
