Aglarond is weird in this for that reason: they mention human-elf marriages being common, but there's no mention of the children of such unions.
That is a potentially cool high Level hook: and the "civilized" neighbors of Thar are all terrible, so ripe for player...intervention.Thar. Valiant orcs fight to defend their territory from ogres, manticores, and perytons in the rocky moorland known as the Thar. Eons ago, this land was a unified orc kingdom. Legend has it that Vorbyx’s Hammer, a great weapon carried by the first king of Thar, lies hidden somewhere here. Thar’s orcs believe that the next orc to wield it will restore the kingdom to its former glory.
