Children of the Night
Five Kings Mountains- The dwarves of the Five Kings maintain significant trade through the west waters of Lake Encarthan, mixing with Varisian, Andoran, and Cheliax traders. The dwarves maintain a modest embassy in Caliphas and shrewdly promote trade relations, knowing that Ustalav may one day recover from the Whispering Tyrant's rule and become a center of civilization in the north. In the meantime, these productive trade agreements help the dwarven kingdom position themselves better in other negotiations with Andor, Kyonin, Taldor, and Cheliax. In return, Ustalav gains modern engineering, weapons and armor, architecture, and other goods. Shudderwood and Leipstadt, in particular, imports large quantities of dwarven ales.
Hold of Belkzen – While Ustalavans are a superstitious lot, they understand orcs are a different sort of monster than the foul things that carried out the Whispering Tyrant's will. Nonetheless, they hate the orcs of Belkzen – their savage tribes, their warrior-culture, the years of raids and crimes against their women and children. These are all things the Ustalav know and remember well. Knowing their enemy, they also understand half-orcs can be a different breed, and regard them much like the twisted births that happen on occasion in Ustalav – known as caliban. Residents in Tamrivena and Ravengro in particular keep a wary eye on the Tusk Mountains for the orc hordes.
Kyonin – Kyonin keeps itself civil if somewhat distant from Ustalav. The legendary crystal and wood architecture of the elven city of Iadara spur the occasional Ustalavan student of art and architecture to travel, though this requires obtaining a number of visiting permits and contacts. The Lodge of the Moon was quietly established through a small cell of elven rangers that regularly collaborated with Ustalavan monster hunters. Most contact with Kyonin is carried out through trade on Lake Encarthan, though.
Lastwall – Ustalavan nobility still remembers when Taldor led a massive effort to end the hundreds of years of torment under the Whispering Tyrant. Lastwall remains as a lasting testament to that sacrifice lasting nearly three decades, and they keep vigil over the region of Virlych, which bothers no one since Lastwall has few expansionist designs, and no one in Ustalav cares much about Virlych. Of late, Ustalav has even more reason to collaborate with Lastwall, because of the activity in the Hold of Belkzen.
Mendev – A hundred years ago the first Mendev crusade was organized by Iomedaen followers in Cheliax, Isger, and Andoran. Since then, there's been a steady flow of mercenaries on their way to the Worldwound. The fortress city of Nerosyan regularly trades with Ustalav, and in fact, relies on Ustalav for many necessities – crops and livestock, mercenaries and building materials. Mendev and Ustalav regard each other as siblings born in suffering, strong and forthright, and too busy with their own affairs for petty betrayals.
Numeria – Kevoth-Kul, the Black Sovereign of Numeria, maintains some terse trade with Ustalav near Karcau, but mostly, Ustalav deals more with migratory creatures such as giant spiders and pythons that crawl their way into Ustalav. Beyond Lake Prophyria, Ustalavan traders can look forward to few settlements of any note anywhere near. It's more likely, Ustalavan traders will make their way a little more northward and closer to Nerosyan.
Razmiran - Relations between Razmiran and Ustalav are strained at best. Some 50 years ago Razmir settled himself in the Duchy of Melcat and gained totalitarian control through arcane spectacle, fear, political adeptness, and effective use of military posturing. First he grew his power by removing parasitic trade guilds, then he grew his popularity through fear and myth. Quickly he began coercing nobles for allegiance, and finally made an utter ruin of the capital of Melcat. Since that time, Razmiran has expanded its borders no less than five times – generally at the cost of the River Kingdoms and Ustalav. The last time was the southwestern portion of Varno, but there Razmiran may have finally reached too far. Initially they were met with little resistance, though many troops were disorganized in the Ustalav mists. While occupying troops were still enjoying the spoils of war in women and ale, and far before settlements could even be established hundreds of troops were murdered in a single, bloody night. The horrific night turned into a week of endless horror, as the invaders' screams filled the air. After just one week they were forced to leave. Since then, for almost a decade, things have been quiet at the border.
River Kingdoms – The River Kingdoms conduct regular trade with Ustalav, bringing spices, clothing, and crops from their varied lands as well as from lands father away like Tian Xia. Tensions do sometimes flare between border patrols of each nation along the West Sellen River, but these are generally bloodless affairs. Riverboats bring goods north to Cesca, Vische, and Karcau. Overland trading caravans routinely move past Corvischior and Thrushmoor to Caliphas, and westward to Lastwall and Varisia. The River Kingdoms regard Ustalav as their grim and private neighbors, while appreciating them for predictability and unusual trade. Ustalav academies draw the scholarly from the River Kingdoms, while mercenaries make good use of the varied and ingenius methods for wounding undead, lycanthropes, and other monstrosities. Other than Galt and its famed Isarn, Brevoy and its capital New Stetvan, and the strange land of Kyonin, Ustalavan cities such as Caliphas (foremost), Leipstadt, and Karcau provide the River Kingdoms nobles with the pageantry they so crave.
