The Travelers brought many creatures to Eana through their portals, the ateaks. These beings, some of which are intelligent, learned to adapt to their new environment but frequently represent threats to natural balance as the druids see it. Bringing aboleths to Eana was certainly the Travelers' worst mistake, and they paid for it with the annihilation of their civilization at the hands of a meteorite summoned by the aboleths that fell in the region currently known as the Eolian Isles.
