Runner_Ruby is a minor, almost irrelevant, Player in The Wanderers Of The Field Roblox group.
Albert and the Forest Overseer are walking through the cave, and both find Runner_Ruby. Ruby says "Greetings, mortal! my name is Emperor Running Ruby!". The Forest_Overseer says he is full of himself and is a loser, and tells Mrflimllam to ignore him.
Later, Albert looks behind, and sees that Runner_Ruby is following him, but does nothing.
Runner_Ruby follows both of them until he reaches Lights_Traffic.
