Mage: The Gun Quarter
Quintessence is the magical energy that flows through all of creation, binding it together and giving it purpose. It is also viewed as a resource for mages as having access to a source of quintessence makes altering reality much easier for any mage. As all things have quintessence in them, it is possible to siphon it out of objects, places, and even people. However, this is a dangerous prospect with often unforeseen consequences.
Most mages prefer to abundant quintessence that springs into existence from a Node. These provide direct access to magical energy that is in excess of what is already in the world.
Quintessence can be stored by the mage if they are skilled in prime magic, or if they possess a powerful avatar. Quintessence can also be harnessed in a physical form known as Tass.
