Sentinel Gates are ancient dwarven devices designed to seal vaults, fortresses, or other important locations. They are imbued with the essence of a deceased dwarf, giving the door an awareness of its surroundings (and a personality). Oftentimes, the doors require multiple successful processes, done simultaneously to open. Passwords, intricate locks, and even riddles are often required.
Sentinel gates are popular collector's items for the wealthy of Erenoth. Some nobles, such as Baron Weston Wimarc of Talmoor, even install the gates in their homes to ward off trespassers or protect their fortunes.
