The Under‑King’s Return; The Rise of Rumuluand

The land of Rothlorian stands on the edge of ruin. From the deep roots of the world, a long‑dormant power has awakened — Rumuluand, once a humble sorcerer of earth and nature, now twisted by the corruption sealed beneath the realm. His mastery of the natural world has been perverted into something monstrous. With a single catastrophic spell, he tore open the boundaries between realms, allowing stone‑born abominations, corrupted beasts, and demons from the Under Realm to spill into Rothlorian like a flood of nightmares. Forests that once thrived now rot in hours. Mountains crack under unnatural strain. Rivers run thick with ash and silt. The land itself recoils from Rumuluand’s presence. At the heart of his ambition lies the Ritual of Ascendance, a forbidden rite from the First Age capable of granting limitless power and a single world‑shaping wish. It was used only once — by an ancient hero who sacrificed everything to seal the world’s corruption deep below the earth. The knowledge was meant to die with him. But Rumuluand has rediscovered it. To complete the ritual, he must claim three relics of the First Age, each hidden in a place steeped in myth and danger: Shale‑Gora, the shattered citadel of the giants, where the Helm of Heramor lies buried beneath centuries of stone and memory. Mitzle‑Dova, the drowned temple swallowed by rising tides, where the Gauntlets of Mar‑Vale rest in the silent deep. San Sorlall, the sunken fortress‑city of the old guardians, where the Carapace Armor of Sanheli remains locked behind ancient wards. Rumuluand’s armies now march toward these sacred sites, leaving devastation in their wake. Villages burn. Caravans vanish. Entire regions fall silent. And above all of this destruction looms a threat older than any kingdom. In the Mountain Forests of Zonida, an Ancient Elder Dragon has awakened — a colossal being whose wings blot out the sun and whose roar shakes the bones of mountains. Scholars whisper that Rumuluand’s corruption stirred the creature from its millennia‑long slumber, binding its fury to the sorcerer’s rising power. Wherever the Elder Dragon flies, swarms of smaller wyverns descend upon the land, tearing apart settlements and hunting travelers with ruthless instinct. The skies are no longer safe. The roads are no longer safe. Even the forests, once a refuge, now teem with corrupted wildlife and prowling horrors. Across Rothlorian, innocent citizens cry out for aid: Eldenford, a peaceful river town, suffers nightly wyvern raids that leave homes shattered and families displaced. Brimwall, a fortified city, struggles under the weight of thousands of refugees, its food stores dwindling as fear spreads through its streets. Karthmere, the proud capital, fractures under political unrest as factions argue over how to respond to Rumuluand’s rise. Vellisar, the great port city, offers supplies and knowledge — but only to those who help defend its harbor from sea‑spawned monstrosities. Luthen’s March, a wandering city‑caravan, provides shelter and trade, yet its leaders beg for help recovering citizens taken by Rumuluand’s scouts. These cities and settlements form a tapestry of hope, desperation, and opportunity. Some offer sanctuary. Others demand assistance. Many stand on the brink of collapse. Each one presents choices that can strengthen or distract from the greater struggle. And looming over everything is Mount Dragoon‑Nod, the Mountain of Wrath — the chosen site of the ritual. Smoke coils endlessly from its peak. The sky above churns with unnatural storms. The mountain pulses with a heartbeat that is not its own. Across the realm, a call has gone out. Kings, clans, tribes, and wandering souls alike are urged to rise. Fellowships form, forged from necessity rather than trust. Ancient tomes resurface. Forgotten relics stir. Prophecies long dismissed now whisper warnings in the wind. The world stands at a crossroads. The darkness grows. And the fate of Rothlorian will be shaped by those who dare to stand against Rumuluand, the Under‑King. This is the story of a land on the brink — a realm where heroes must rise, alliances must be forged, and ancient forces awaken once more. The journey will lead across wild frontiers, through forgotten ruins, into besieged cities, and ultimately to the storm‑crowned summit of Mount Dragoon‑Nod. There, at the ritual’s final hour, the path will diverge. You may fail, and watch the world fall beneath the Under‑King’s dominion. You may prevail, ending Rumuluand’s reign and saving Rothlorian from annihilation. Or you may claim the ritual’s power for yourself, seizing the wish that can reshape the world — for good, for ruin, or for something no prophecy has foreseen. The mountain waits. The ritual stirs. And the story is yours to uncover.
