This is adventure 24 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.
Putting It All Back Together Again
A Get Ready, Get Set, Go! Classic D+D adventure set in Heaven and Hell
In order to fix the mortal realm the PCs need to hatch the Egg of the Dragon… in the fires of Hell!
The Final Chamber of the Temple Basement contains the spirits of The Dragon and her Mate. They tell the PCs that their offspring needs to be hatched, and returned to the mortal realm. In order to allow the egg to develop it must be warmed in the fires of Hell. Conveniently there is a direct Gate between the two. Souls get mixed up sometimes. It happens. The Gate is however highly militarized, and with the loss of the immortals on both sides, the troops are disinclined to let some mortals just walk on through.
The PCs might also have access to Gate Magic, however incursions into Hell (be the living) are generally met with resistance. Of course, Hell is a big place, and most of the Demons and Devils are rather upset by their missing Lords. They express this upset by trying to become the New Lords of Hell. Because of this Hell is a much more chaotic place than it usually is.
Once in Hell the PCs will need to find a nice quiet spot to warm the Egg.
Negotiating with Devils is always a chancy prospect. They will drive a very hard bargain, especially as they don’t see much point in letting the PCs in. On the other hand, if the PCs offer something of remarkable value, they just might be willing.
Keeping the Egg in Hellfire for an hour will be enough to get it to hatch. And when it does, it's an orb of blazing blueish white light that says "Thank you" before whiting out everything. When the PCs' eyes clear, they're back in the main square of The City.
