THE GEOGRAPHY OF UHL
Merrow Woods

The Merrow Woods is the largest forest in all of Uhl, a vast expanse of ancient woodland stretching hundreds of miles across the continent's interior. Bordered by the Vernesse Steppes to the west, the Blasted Land and Shadow Downs to the south, the eslar kingdom of Panthora to the east, and the Ugull Mountains to the north, the forest dominates the landscape between these disparate regions like a green sea unto itself. Its towering canopy, formed primarily of massive blackwood oaks, rises in some places to heights exceeding two hundred feet, creating an elevated world of interlocking branches and dense foliage that blocks much of the sunlight from reaching the forest floor. Beneath that canopy, the woodland teems with life both mundane and dangerous. Numerous streams, rivers, and natural springs thread through the undergrowth, sustaining an ecosystem as rich as it is perilous, for the deeper reaches of the Merrow Woods harbor creatures that have kept even the most seasoned hunters and explorers at bay for centuries, wendigos among them.
The forest's sheer scale and the dangers lurking within its depths have made it a natural barrier between the civilizations surrounding it. Few roads penetrate its interior, and those that do are seldom traveled without considerable armed escort. The krill, a reclusive bipedal feline race organized into six fiercely independent tribes, have claimed the Merrow Woods as their homeland for millennia, building their civilization among the highest reaches of the canopy where other races cannot easily follow. Their presence, combined with the forest's predatory wildlife and trackless interior, ensures that the Merrow Woods remains one of the most inaccessible and least understood regions of Uhl, a place where the ancient world endures largely untouched by the advancing age.
Grimmere Swamp

The Grimmere, known to outsiders as Death's Head Swamp, is a vast and treacherous wetland stretching across the lowlands between the eslar kingdom of Panthora and the Shadow Downs to the north, the Freelands to the west, the Hollow Hills to the south, and the Alderden Mountains to the east. Comparable in size to the Blackwood Forest, the Grimmere dominates its corner of the continent as an impenetrable morass of stagnant waterways, quickbogs, and dense thickets of gray swamp trees whose tangled canopies trap heat and moisture in an atmosphere so oppressively humid that even seasoned travelers find themselves gasping for breath within minutes of entering its borders. Two rivers feed the swamp's sprawling interior: the Rotwater, which descends from the Shadow Downs through a series of silted channels before losing itself in the wetlands, and the Mireborn, which winds northward from the Hollow Hills carrying mineral-rich runoff that gives portions of the swamp its characteristic brackish, iron-tinged waters. Together, these tributaries sustain an ecosystem as hostile as it is vast, where venomous serpents, disease-carrying insects, and predators both natural and unnatural thrive in conditions that remain deadly to most other living things.
The swamp's grim reputation is well earned. Its name among the peoples of the Freelands and the Four Fiefdoms — Death's Head Swamp — speaks to the near certainty of death that awaits those who enter unprepared, and even the prepared rarely fare much better. Beneath the murk and mist lie the ruins of Il'kell, an ancient empyrean city that flourished thousands of years before the Age of the Old Gods, when the land was fertile and the climate hospitable. The slow transformation of the region into swampland claimed both the city and the civilization that built it, leaving behind miles of vine-choked stone, crumbling columns, and sealed laboratories that still hold secrets and dangers in equal measure. The ruins are considered sacred ground by the sitheri, the fierce serpentine race that has claimed the Grimmere as its homeland for millennia, and trespassers who venture too close to Il'kell's remains rarely live long enough to report what they find there.
The sitheri are the undisputed masters of the Grimmere, organized into ten territorial broods, each led by a brood mother who commands absolute authority over her tribe. These cold-blooded predators are uniquely adapted to the swamp's punishing conditions, thriving in an environment that serves as both sanctuary and fortress against the outside world. Their perpetual warfare with one another over territory and resources has prevented any single brood from achieving lasting dominance, yet their collective presence ensures that the Grimmere remains one of the most dangerous and inaccessible regions in all of Uhl.
