I imagine that five lairs won't be enough for the World of Samardan Campaign Setting, so I'm going to create five more to post. Please feel free to let me know your thoughts on them in the comments section.
(Hex) Burahiko's KeepPansanu Yatan Burahiko, an aspiring warlord, is forging a new settlement in the wilds under his rulership. Although the Pansanu has grand plans for the region, he has only managed to construct a small keep thus far. His original support has long since abandoned him, and so Pansanu Burahiko has taken to raiding nearby settlements in order to further his aspirations.
(Hex) The Forgotten Army of Dankahena the ExileWhen Raganu Pekadevi Rekatur, the Lord-Emperor of Torkobalem, ascended the throne, he sent into exile anyone who might contest his right to rule, including his younger sister, Doganuba Dankahena Rekatur. Now, Dankahena the Exile has gathered an army of disenchanted loyalists under her banner, as she prepares to take action against her brother and claim the throne. Gossips say she has recently taken a new warlord as her right-hand man. Little is known of this mysterious man, save for his superior tactical knowledge as evidenced by her recent military successes against outlying forces of Torkobalem.
(Hex) Obsidian Halls of the Kelsh-RaganuAn abandoned complex, decorated throughout with obsidian tiles, has become known as the Obsidian Halls of the Kelsh-Raganu ("Demon Emperor"). According to legend, the king of all demons lies buried in the depths of the complex, and the nearby volcano shall remain dormant so long as the Kelsh-Raganu remains undisturbed. A band of mercenary kelshrani use the complex as their base of operations on the surface, taking advantage of their appearance and the legend of the Obsidian Halls to subdue nearby settlements through fear and intimidation.
(Hex) Sanctum of Sen LusasananBy all accounts, Sen Lusasanan is an insane mystic consumed with understanding the nature of life and biological enhancements. Toward that end, he has claimed an abandoned stronghold in the wilderness as his own, where he performs terrible experiments on captured victims. His army of patchwork monsters often roam the surrounding regions in search of new victims and esoteric supplies to further their master's hideous work.
(Hex) Warrens of the Marsh FolkThe human tribe known simply as the Marsh Folk dwell within these unusual warrens, cut off from the rest of civilization. Like many remote cultures, the Marsh Folk entertain some customs that others would consider taboo, particularly cannibalism. Indeed, the Marsh Folk have developed a number of delicacies based the flesh of husrani, rakrani and particularly sarrani people. As these races are understandably rare in the area, having been hunted out, the Marsh Folk hunting parties occasionally make excursions into more settled areas, looking for new "stock" for their kitchens.
Standard Disclaimer: As I have not yet decided where to set these particular lairs on the map as yet, I've left a placeholder to remind me to come back to this in the future. Later on, I'll replace (Hex) with the actual hex location, when I put all of this together into a single document.
