Obdurium

Obdurium is a pale violet metal which is harder than adamantine. This incredibly rare metal represents the pinnacle of nonmagical metal strength. It is also nearly prohibitively expensive, building with it costs ten times as much as carving stone walls and sixty times what a normal wooden wall would cost to build.

The doors leading to the Godtrap in Zagig's Prison beneath Castle Greyhawk are made of obdurium.
