Gravimancy plays a role in levimancy and flight magic. 
Magic users skilled in gravimancy are known as gravimancers or dynamo mages.

Gravimantic Spell Types:
Conjure Gravity – The creation, formation, or generation of gravitational force (of varying strengths) purely from the aether, as conjuration magic.
Manipulate Gravity – The change of the strength or area of a gravitational field.

Gravity Ravine – The creation of a line of gravity that acts as a "ravine" for objects to be pulled toward, often literally breaking the ground into a ravine like fissure in the ground.
