Empire of Lightrune
The jungles on the southwestern border of the Empire are famous for their giant lizards and roaming orc tribes who have domesticated some of them. The land is currently under Imperial control, but the orcs who make up the majority, under their Great Warlord, are fickle and may rebel at the slightest loosening of Imperial control. Besides orcs and dinosaurs, the Ironthorn Jungle is also a source of poison: a large variety of poisonous plants and animals provide a deadly cornucopia for assassins and death dealers of all sorts. The very proximity of the Ironthorn Jungle gives the entire southwest region of the Empire a reputation for producing assassins and being paranoid about accepting food or drink without it being tested by someone else first.
Sites of Note
Kilnorra Tog: Kilnorra Tog is a temporary city formed by the orc tribes twice a year. Under the banner of peace, orcs of many tribes gather together on the same site, to exchange goods and animals, arrange marriages and other alliances between tribes, and brag about tribal accomplishments. Those that attempt to disturb the peace are killed summarily. Most of the tribes of the Ironthorn Jungle are invited to Kilnorra Tog, with only a couple considered vicious enough that even the other orc tribes want no dealing with them. However, usually only about three quarters of those invited are at attendance. Some show up just to leave because a hated rival got there first, others are too far from the site to make it in time.
