Talia the mark in draconic reads 'evil'.       Now that other sigil infused into the door in silver.  Is in celestial, if any can read it.   It is the mark of 'undead'.<br/><br/>Fortunately no trap is on the door.   The key fits and the door unlocks.   But it does not open.   It then be realized the door has a arcane lock upon it.    Either a dispel magic or a knock spell will suffice to open the door.   However, if the group proves not to have either.  Brute strength can be attempted.  (Strength DC 28 to open the door)
