The offer that Shardu gave to Gobruk was something even Elaina was not expecting. Genuinely suggesting that the whole tribe of Greater Ogres work on the farm is not a problem. In fact, she could use some heavy lifters to help her from time to time on the farm, but that doesn't mean she needed them all the time. And considering that Greater Ogres don't need money, they will ask for a different kind of wage for their work, like instead of money, they would instead demand food and perhaps a safe place to stay in exchange for the labor.
However, that alone is a big problem considering that the farm is near the public. For the regular people who are not too well-versed with monsters and other entities living in the forest and with how big Greater Ogres are, they are seen as monsters by other people, and there might be some panic if they appear immediately.
