The Rime-Shell Fortress

Overview & Aesthetic

The Rime-Shell Fortress is a surreal and beautiful architectural wonder. It is a massive fortress carved entirely from the interior of a gargantuan, hollowed-out glacier. The walls are translucent, shimmering with a pale blue light from the sun filtered through hundreds of feet of ice. The air is freezing, and every surface is covered in a fine layer of frost. The furniture is made from a mixture of bone, fur, and magically-hardened ice.

History & Lore

The fortress was built as a hidden refuge for the Frost-Mantle rebellion. Because it is carved into a moving glacier, its location is never static, making it nearly impossible for the Northern Kings to find. The ice of the fortress is reinforced with ancient Aether-runes that prevent it from melting, even when the hold's forges are running at full capacity.

Environmental Hazards / Mechanics

• Extreme Cold: Characters without cold resistance must succeed on a DC 12 Constitution save every 10 minutes or gain one level of exhaustion.
• Slippery Floors: Most of the floor is ice. Moving more than half speed requires a DC 12 Dexterity (Acrobatics) check.
• Ice-Rockets: The fortress is equipped with defensive projectiles made of magically sharpened ice.
