You'll admit while playing Darksiders you spent a fair amount of time wondering what it would be like to travel with War and try to awkwardly flirt your way into his heart.

(PROTOTYPE) The Charred Council must recognize the part of the prophecy where humans are prepared to face demons and angels at the End War. The End War has come, but they are not ready. To rectify this, they send someone who is skilled with war almost as well as War himself who is...preoccupied. For this, they send Strife

You're at home whenever the Horsemen decide to visit, for example. [post Darksiders / Revival Earth. Polyamorous! Protag traveled with War during Darksiders and kisses all the Horsemen because heck yeah.]
