Giant's Minion Lugonnes:
After you destroyed Sakum, Embryo created 2 clones of the monster named Belos and Kampf.
When I last saw Belos, he was heading to the Ketra Orc Outpost. It seems like the Ketra Orcs and Embryo are working together, with Belos as their link. You and I must end this alliance.
There is much to be done. Prepare yourself and speak to me when you are ready.

- Note: You can develop yourself through quests and hunting at the hunting ground of Ketra Orc Outpost. You can get the next item, Kekropus' Letter, at Lv. 81.
