"War of Ologh" Campaign

This is the first campaign that the group will be playing starting this summer (most likely 6.21.2014, but will make sure this day is a fine start for the others). It starts off with a battle between a stronghold of Orcs, Half-Orcs, Humans and Trolls against a city of Elsse, whose inhabitants include Elves, Half-Elves and Humans (along with the adventurers of this campaign). The main villain of the campaign is Eiod, the Half-Orc leader of the stronghold. He is a servant of Ologh, the demon god of Revenge, Deception and Destruction. He gained his help to take revenge on a group of thieves who are in the city of Elsse who had killed his father, raped and murdered his mother, and then raped all five of his sisters, all in front of him. They were illegally sold into slavery in Elsse. Eiod sees the whole city as guilty and wants to destroy it and get his sisters with Ologh's help. Though does Ologh have ulterior motives? We shall see...
