Solar Training Ground from a recent event gives Orc Warriors, but can't buy or craft at the moment now that event's over.

Thanks to both of you. I will live without Orc Warriors for now.the Shrine of Champions Ancient Wonder gives them. But it only becomes available in chapter 18 or 19.
Yep, I get gruff orc warriors from brown bear. I get 1,920 every 48 hours.Orc Warriors I think I get those from Brown Bear.
