The Guild of Illuminators is a society of Illuminators founded in Tanchico and are a guild to hold and protect the secret of making illuminations (fireworks). The Guild were known to go great lengths to guard it's secrets, even to the cost of murder. No one not born into the guild is allowed access to their knowledge. They usually provided entertainment for lords and kings, but simpler forms of fireworks were also sold to the general public (accompanied with dire warning of disaster and destruction following attempt to open them).
