Kami

Kami are "great spirits", specifically the spirits that associate with all things in the world of Kamigawa.

Description
Kami come in an overwhelming variety of forms, even among the same "species" of kami, and their brand of magic is mysterious and beyond anything mortals have conceived. The greatest kami of all are the five myojin, rivaled only by the mighty O-Kagachi. It was because the theft of O-Kagachi's scion, that the Kami War began.

When the kami manifest into the ordinary world, their manifestation is a bit unstable and creates strange energy objects orbiting around them.

Background
According to Brady Dommermuth "[t]he overarching premise of the Kamigawa block is 'Shinto gone wrong.' In Shinto, a belief system indigenous to Japan, everything has a kami. Kami are gods of a sort; they’re the eternal essences of things, people, places, ideas, and so on. To give Kamigawa its own distinct look, as well as to reflect the fact that the plane was in turmoil, we concepted the kami as bizarre creatures that look out of place in the natural world, as though they couldn’t even realistically exist within it."

When the Kami War broke out, the kodama appeared to go dormant, sinking its roots into the ground and becoming unresponsive. Unfortunately, the reality was much less peaceful. The kodama was spreading its roots through the territory of the East Tree, and from the ground burst a new kind of spore unlike any the monks had ever seen. These spores all struck at once, latching onto humans and syphoning their energy to create new spiritual growths. At the end of the twenty-year war, the kodama sank into dormancy once more. While it hasn't stirred since, the remaining monks still pray to it nervously—from a safe distance.
