You descend ten levels and follow a tunnel which eventually ends at a sealed door, carved from a solid slab of coal-black steel. Engraved into its surface are several runes and glyphs of power which you immediately recognize to be magical. They have been placed here as a warning to anyone foolish enough to attempt a forced entry that such an attempt is likely to result in their death.
Intrigued by the warning, you examine the runes more closely. As you are doing so, you suddenly hear a sound in the tunnel and turn to see two figures approaching. Hurriedly you retreat into the shadows, masking yourself with your camouflage disciplines to prevent your detection, as the two figures draw closer to the door.
