Herald of the Moon is a decent adventure, it can be ran anytime during the Rage of Demons story line. The first part introduces the character to the situation and gives them a chance to talk to the NPC and do a bit of roleplay. The second part includes the travelling to get to the location they need to be, they have to pass through a forest that contains danger and encounters. The last part has the characters arrive at their location and begin the whole dungeon crawling thing to achieve their goal. It has a bit of surprises but the combat is not that challenging if the characters play smart and are familiar with combat. This adventure can be considered a short side story in the Rage of Demons story line and it doesn't really affect the entire story so it can be ran and played anytime quite easily. The only thing that connects this to the Rage of Demons story line is the notable locations that the characters are in or will go through.
