Taking a quick jaunt into the ethereal plane, the demon did notice something off. Normally when in such a ghastly place objects from the material plane appear to just be specters of themselves. The oddly colored green stones looked very solid in this plane as well. They felt solid too as when walking through the door worked as well as it would in the material plane. Which is to say the bard walked into a solid mass of stone before bouncing back.<br/><br/>The door did not have any simple mundane mechanism for opening. Given the nature of the tomb, and all the magic in the air, the door itself probably operated on magic as well.
