Radmiium

Radmiium is a Colorman alloy developed during the first era.
When a room's walls are coated in radmiium, it prevents teleporation in or out of the room; making it useful as an alloy meant to keep magical prisoners in their cells instead of allowing them to teleport out.
The Crypt of the Anchor is one such room that uses radmiium.
