Door

A fixed device that blocks an opening unless opened and sometimes has a lock. Also known as a "gate" or "portcullis". Some portals act like doors, but most don't. Some doors have fixed devices on the inside to open them without a lock, these devices are usually levers. Many doors are only for decoration and do not lead to anything.

The door into Arcatraz (an instance wing of Tempest Keep) is made of energy beams, but it can be unlocked with Lockpicking.
