Dark Covenant of Fire

The Dark Covenant of Fire can be used to command the Dark Oracle of Fire, but each individual only gains one such command. While in possession of the Covenant the bearer cannot be harmed by the Dark Oracle, until they say their command of course. The Covenant takes the shape of a small lantern. 

Tamori
In 1157 the Covenant was used by a Phoenix and a Dragon to invite the Dark Oracle of Fire Tamori to attack their respective clans. The Phoenix used his command to make Tamori incite war between the two clans, but had extended the protection granted by the Covenant to the Dragon over himself. Tamori was happy to attack both the Dragon and the Phoenix clans, but swore he would see both of the instigators dead.
