The Doorman is the gifter of pearls of protection, allowing players to leave the dungeon as a swift action whenever they believe they are in trouble.
He also only speaks via telepathy, and imposes a rather powerful figure across anyone who is with him.
It should become extremely clear that if this is NOT a developer's character, it is an very favored NPC at the least.
If anyone attempts to break the rules of the Dungeon Tower, a copy of him (exact clone) appears to exact punishment for 1 minute.
The Doorman's telepathy functions as the level 8 psionic power listed in the link provided.
