Yawny Goodknight is a Sentinel Guard NPC located at Sentinel Checkpoint in Nexus Tower. He plays no role in the game other then being part of the achievement Sleeping On the Job. To get the achievement, players must use three quick chats that have loud noises to "wake him up." Morty Mizzenmast in Pirate Camp servers a similar role to him, though there is no achievement for Morty.
