Witch

A young elf girl dances amidst a flurry of multicoloured lights, all the mortal eye can perceive of the spirits dancing joyfully alongside her.

An old halfling man slices his wrist, allowing the blood to pour on to a circle drawn in ash on the floor. From the ashes rises a small cottage, the formerly burned wood being dragged back to life and arranged into a shape of the man's choosing.

An orc army stops it's march through a sacred forest at the sight of a lone human woman. Their joy at the prospects of some sport quickly turn to horror as their life force flees their bodies, and that energy is then used to pick off the remainder.

The nobleman goes through ancient tomes, trying to learn of a way to barter with the fae for their favour, in order to boost the wealth of his lands. He gets what he bargained for eventually... and a lot more.

Bridge between Worlds Witches, through study, chance, or birth, gain the Sight, the ability to see the spirits of the world around them. Everything, the trees, the rivers, the ocean breeze, all of it is alive, and far more intelligent than one might expect. Normally, these spirits mind their own business, but if a human can see them and follows the ancient ways appropriately, exchanges can be made. This often takes the form of a small portion of the Witch's life force, so small it can easily be recovered by resting, but to a lesser spirit, this is more than enough to both create a magical effect of some magnitude and leave some leftover for themselves. However, some witches discover darker paths, tricking and coercing spirits into doing what they want, or taking the energies for their spells from their foes by force, usually with the aid of darker spirits like the vengeful dead.
