The Destroyer
there should be a quest npc a bit like the fisher that makes you get wired fish but this npc wold make you go to certain places and make you get a exotic item and this could bring a oportunity for small exotic bioms and wired places other wise wouldent suite the game as a full scale biome also making the oportunity for more exotic items and rewards expand on the idea if you wish this is only a idea
