Captain Andrei:
Giant's Minions have been chasing after Embryo for a long time. They recently found out that the organization created clones of Sakum and one of the clones went to the Ketra Orc Outpost. That's all I know. For more information, you should talk to Giant's Minion Lugonnes in the Ketra Orc Outpost.
To get there quickly, use the Scroll of Escape: Ketra Orc Outpost I gave you. You could also ask a Gatekeeper for help.
