Sentinel 868

Sentinel 868 is an Ice Golem created to guard the door to the dam control room of the ancient city of Anodunos.

When the Avatar met him in Ultima Underworld II it became clear very fast that Sentinel 868 was totally oblivious to the fact that Anodunos had stopped existing a long time ago. While he told the Avatar what was behind this door, he warned him/her not to try to pass. However, the Avatar had to pass, and so was forced to destroy the Sentinel in combat to get the key to the door.
