The Shard of Regulus

An artifact blade forged in the heart of the star regulus & blessed by the sun goddess Amaterasu. This weapon unleashes divine flames that only destroy pure evil and can be used to cleanse the impurity from other beings and objects that they come in contact with. The weapon however does hold a "Wrathful God" mode that briefly spawns a miniature star roughly the size of a grain of rice. that mini star is super massive enough to cause gravitational calamities on planets, and create bursts of heat as hot as the surface of the nearest star. This version of the swords power is unleashed in order to the smite any foe, evil or otherwise.
