Katu and Neit

"And war unites what lies at odds, makes Keit and Natu lock their shields. With blazing spears in equal stride they march, bronze-helmed and dreadful is their sight. In peace they fight, it is in war the brothers join." - Kleïs' Hymn to War

Katu and Neit are the Twin Gods of War. While Katu represents a more thought-through, strategic approach to battle, Neit represents the passion of battle, bordering on bloodlust. According to their myths, they fight each other almost as often as they fight alongside each other.
A number of myths around the twins caution warriors against turning to only one of them. They tell of generals standing alone when their troops leave them as they did not sacrifice to Neit; and of berserkers being overwhelmed by opposing forces because they lacked Katu's wisdom.

Divine Symbols & Sigils

Crossed swords or spears; helmet and shield

The twins are most often depicted as two armed young men, though their gender differs in older myths and depictions, where they also appear as two young women or fraternal twins of different genders. 
Since they both wear helmets and carry weapons, they can often only be told apart by their posture or expression, with Katu watching stoically or seeming to give out orders, while Neit is charging forward, features twisted in fury - unless they are fighting each other.
