This page is a Code written in Lawbook, which is a lawbook created by AriEpik.
Code Red means "something painful to do with fire", as written by SpeedoThreeSixty in WIP Chapter 8 - Griefer Rebellion in Lawbook by AriEpik on page 1, Codes. Lawbook by AriEpik was taken out of Mega's hands by Speedo curiously in Chapter 7 - A New Arrival. Mega doesn't seem to mind. Also, before he wrote Code Red, he also wrote Code White, which means "any mob horde".
