Kataki

Kataki was a spirit of Kamigawa made of weapons and bound in armor.

History
Before the kami went mad, Kataki was to whom the smiths prayed as they forged weapons, to whom soldiers sharpening their blades whispered. Small shrines dedicated to the spirit were kept in armories across Kamigawa. Kataki was recognized as War's Wage, for it was the great protector-spirit that kept a warrior's armaments and armor intact.

One small village gained the enmity of Kataki when it took in a dying warrior. This man had offended Kataki and so the kami came to the village, seeking vengeance. One villager, the guard who had found the dying warrior, slew the stranger in an attempt to appease the kami. Kataki then claimed that the villager had robbed it of its vengeance and turned on the villager. Such is the madness of the kami for nothing could have been done to appease it.
