The Ninja Sentry was a pre-alpha NPC in Forbidden Valley. With the Dragon Forge under attack by Darklings, the Ninja Sentry would have sent players to find and help the Bricksmith. After completing the Bricksmith's missions, he would have sent players back to the Great Tree to speak with the Ninja Sentry. There, the Ninja Sentry would send players to speak with Numb Chuck in the Dojo, advising that hidden bouncers in the area might be shortcuts.
