At the end of the war between the Demons and the Humans the Hero Dawn, sacrificed his life to seal the demons away forever leaving many people heartbroken and crestfallen, but none compare to that of his adopted brother Cass. Cass was raised a weapon, taught only destruction. Death is his craft and blood his fuel, until he met Dawn. Dawn took Cass under his wing when Cass was young and raised him ever since, teaching him to use his strength and powers for good and to support others, how to live a normal life, to love and laugh. He even got him a small cottage that double as a library to keep him away from fighting when he can. But with the death of Dawn Cass has retreated to the cottage and hasn't really been heard from since. A few people old friends of Dawn check in on him every so often but he's often unresponsive or too upset to speak.

And now along comes you. A vagrant? A diplomat? A lost explorer who knows. And what you do next is up to you, will you be a villain and rip away the small bit of happiness he has left or be the hero and offer him comfort to get him back in fighting form.
