Elom is a hidden character located in a cave across a river west of the entrance to the Golden Hills tunnel. Leif's icicle skill is required to reach him. He gives you the quest "In Search of Something" where he requests you to go find a "Golden Paradise."
The "Golden Paradise" refers to Golden Hills, where the goddess Venus resides. There, a pink ant named Tekci offers to help fulfill his request.
The two bugs decide to stay in the cave together, and Elom gives you a Lore book in return.
