Well, arguably, that is the specialness of FR---how it loots other settings for anything vaguely interesting and adds them to itself.MoogleEmpMog said:As shock troops purchased from Eberron by Thayan spelljammers, which the Red Wizards desperately want to reverse-engineer? Yes.
As home-grown FR natives? No.
Orcs aren't native to Krynn. Warforged aren't native to Abeir-Toril. Draconians aren't native to Eberron. Mixing and matching just reduces the specialness of each individual setting.
