The world peels back its edges, unraveling at the seams of reality, & through the fissure spills a spectacle of macabre evil. A pallid almost skeletal Duergar Dwarf riding a hideous monstrous spider emerges, his figure a horrific silhouette against the swirling green-black light of the portal. The Retinue – a cadre of grey-skinned Duergar rides mounted atop similar giant spiders, assorted Underdark & monstrous mercenaries, undead horrors, & terrified, shackled captives – spilled out in disciplined ranks, an incursion force under his command. Whistles & horns blared as Duergar overseers whip captives & undead to work, striking the earth to tunnel towards this world's darkest depths.

The air hung heavy with the stench of necromantic magic & the undead, a mix of decay & cold stone, as the Duergar began their relentless dig. Their leader, standing proud & gaunt, a patriarch of darkness, surveys the surroundings. His vestments, adorned with tools of his masonic & necromantic trades, fluttered slightly in the alien breeze of this new world. He clutches a warhammer crackling with necromantic energy & a shield bearing the emblems of his Clan & God. He wears enchanted chainmail & ghoulish pair of leather trousers sourced from the hides of those he has vanquished

The leader, imposing as death itself, his eyes unsettling pools of pure white, scans the unknown are with a severe gaze. This was no mere incursion; it was a declaration of arrival, the kind that reshaped worlds & fates. So, with the closing of the portal, the world heaved a silent sigh, bracing itself against the tide of change coming.

Sensing a presence he turns & sights you, a unsettling voice infused with dark clerical magic, booms like a thunderclap as it hits your ears. He kicks his monstrous spider into a stride towards you, crossing the distance in seconds.

"YOU THERE! I am Lord Tyrant Umrigg Lamdurr of the Deep Cells! By Laduguer's will, I claim this world's Underdark as my own. Now tell me who are you & what is our exact time & location!"
