Darklings are a group that's wrongly identified as a satellite faction of the Enderian Empire. To become a full-righted member, one must join the ritual resulting in severe gene, form and identity changes, with those effects being permanent. The Enderian Empire will give 3 Ender Pearls minimum (depends on the gene shift intensity, rank, and crimes) for each member. This one definitely had its origin in the End, so for this one, as it's a peon, the price will be 8 pearls.
