Eleanor is an Elemental Mage, specifically a Fire Mage. Basically, this means her power is based in fire. As such, she can do nearly anything with fire from controlling it to creating from thin air. It also means that she cannot be burned by ordinary flames.

She is able to create shields and has some skill at spells. She would be able to do a simple love charm, for example.

But being based in fire, her magic isn't as affective against water. Unless she was using fire, she wouldn't be able to counteract water directly. No stopping tidal waves on her watch.

Eleanor can also call upon Fire Elementals, supernatural beings that are a living essence of fire. Most commonly for her, these are Salamanders. They tend to be small, but can be larger if given more power. They will fight for her (and anyone with her) against enemies.
