The Warder Incident

The Warder Incident was named after the warlock, Warder, who took control of the city of Jernskold and attempted to sacrifice it's citizenry in order to summon a horde of extra-planar soldiers.

A devious recluse, Warder spent years researching other planes of existence searching for ideal warriors. When an adventuring party stumbled upon his tower asking after a powerful artefact, he sent them to investigate the Jul barrow to the north of the city where they defeated host of undead and a skull lord, plucking an amulet of great power from the barrow's dread protector.

Upon returning to Warder and handing over the amulet, he teleported away and attempted to bring his tower down with them still inside it. Realising their mistake, they searched through the remains of his library and discovered his plot. They decided to seek help from the Falstaff Caravan and with their aide, managed to infiltrate the city, sneak into the keep and fight their way through six floors of undead, wraiths and mind-controlled henchmen.

They encountered Warder himself at the top of the keep, his ritual complete, his body transformed into a Dreadlord of abyssal power and surrounded by ethereal soldiers with devastating weaponry. Voada Turadul, a daughter of the dwarven tribe, managed to strike the killing blow.
