Isger

 Isger  is a vassal state of Cheliax. In the eyes of Cheliax it is not so much a sovereign nation as a glorified trade route. Isger was founded in 2133 AR, after Taldor's Seventh Army of Exploration defeated its indigenous inhabitants, the Isgeri. The Isgeri fought the Taldans tenaciously, but were eventually conquered and pacified. In recognition of their great courage and determination, the Taldan crown named their newest province after the tribe. As a vassal state of first Taldor and later Cheliax, Isger's natural resources were heavily exploited over the millennia. Eventually the only thing the state had to offer its imperial masters was its valuable location as a trade route between Cheliax and the rich nations bordering Lake Encarthan to the northeast. This route led up the Conerica River from Cheliax, past the capital of Elidir, and from there overland into the nation of Druma. As a result, the Isgeri government has concentrated most of its resources to the communities on the Conerica, leaving the rest of the nation to become an impoverished, bandit-infested hinterland. 

Isger suffered terribly during the Goblinblood Wars when hundreds of tribes of goblinoids (including powerful hobgoblin warlords and their goblin slaves) emerged from the Chitterwood in southern Isger in 4697 AR, killing all in their path. Isger's army was unable to stem the invasion. The goblins were eventually defeated by an unlikely alliance of military forces from neighbouring nations, including the Eagle Knights of Andoran, the Hellknights of Cheliax, and the Mercenary League of Druma. Each fought to keep the goblinoid forces from overrunning Isger and spilling out into their respective countries.[4][5][2] With the enemy armies defeated, the victors put much of the Chitterwood to the torch in an attempt to deprive the goblinoids of a home. Although thousands of goblins died in the conflagration, many fled into the caverns below the forest and survived.

After the war
The Goblinblood Wars were marked by heavy losses on both sides, especially among the Isgeri, and thousands of orphans were left to fend for themselves after hostilities ceased. Their numbers even continued to rise in the post-war period, as chaos and banditry swept through Isger's hinterlands. The only organization who stepped in to help these orphans was the church of Asmodeus supported by Cheliax's House Thrune. They built a number of monasteries throughout the country where they fed, clothed, and indoctrinated Isger's youth into the faith of the Prince of Law. The most famous of these is the monastery run by the Sisters of the Golden Erinyes, where children are not only schooled in infernal philosophy and politics, but also in hard-to-master martial arts.

Gillamoor Plague
Trade caravans have recently reported strange sightings near the village of Gillamoor on the edge of the Chitterwood. It seems that its inhabitants were transformed into ravenous undead, and that this so-called Gillamoor Plague has spread to other nearby villages as well. The plague is blamed on necromancers and powerful priests of Urgathoa, who are believed to have taken advantage of the chaos in Isger's hinterlands following the Goblinblood Wars. Some believe that the most powerful of those infecting the countryside is a diabolist named Lady Kaltessa Iyis, a cleric of the archdevil Mammon. Lady Iyis is even rumored to secretly control Isger's rulers and be building an undead armies from the dead of the Goblinblood Wars.
