This is adventure 14 of 25 that is roughly designed to take characters from level 1 to 25 that I will be sharing over the month of September. These posts are a part of Asshat Paladin's OSR Short Adventure Challenge, and utilize his Get Ready, Get Set, Go! format.
Lastly, don't forget to vote on my new poll - What is the Defining Element of Steampunk?
A Get Ready, Get Set, Go! Classic D+D adventure set in the PC’s Castle
A mysterious stranger arrives with a key, an offering to trade it for his master who desires the magical pendant. Players being players, someone will eventually put the key into the lock, opening the gate, letting all hell breaks loose - literally!
The key, once inserted into the lock, will glow white hot, and the arch will begin to glow with a red light. The portal will flash open, knocking back anyone within 15 feet. Anyone looking into the portal will find themselves looking straight into hell. Hot sulfurous winds will blow from the gate, and demons will begin to emerge.
The mysterious stranger is actually a chaotic cleric, and will attack the PC’s for the pendant if they are unwilling to trade for it. However his goal is not to gain the pendant, but to get the key into the PC’s hands without raising their suspicion, as he needs the holder of the Dawnstone to open the Hellmouth. The key will be drawn toward anyone holding the Dawnstone, and the lock will resist the key if the Dawnstone is not also present.
Removing the key will stem the flow of demons and close the portal… mostly. A tiny crack will constantly emit a foul red light.
