48 Sacrifices

History
Before Tet declared the surviving cluster of Corone Dola as Imanity, humanity existed with no reason to live but only to survive each living day of The Great War.

Families and individuals who survived gathered inside a cave isolated from the other races. With no information or detection to probable danger, a reconnaissance group (Riku as their leader) roams the surrounding area in search of remnants or ruins left behind the other races in order to assess the war.

However, places they traveled to lie traps and harmful entities such as Phantasma puts the group in danger. Having no change of survival, individuals are left behind to be sacrificed in order for the group to survive. The victims total to 48 hence, the name 48 sacrifices.
