Aha! I know why they’re called Reapers… Ataron-dust comes from Serpent Grass, and the grass grows much like wheat does, and when it’s fully matured it needs to be reaped. The first people to really discover the addictive and euphoric properties of Serpent Grass, the first people to create Ataron-dust, were the reapers – the people employed to reap the grass when it’s ready. Ta da! That works! I knew they were called Reapers for a reason!
