Someone on twitter posted this earlier and it peaked my intertest.
A world primer mash up of Ravenloft and DragonLance. Horror adventure in the Dragonlance world with Ravenloft monsters and styling… Lord Soth would not need any changes, but I think it would be fun to do a darker version of DragonLance.
I think it would make a good mash up for a halloween adventure/special world primer! …
I don’t know much about both settings but it sounds interesting! See you on the Beer & Pretzel Discord server? 
*A darker sunset version of DragonLance. Ravenloft, thru the Demiplane of Dread, mists have reached the planet of Krynn. The Demiplane is connected thru a short plain of mist located on the northernmost tip of the northern wastes of Ansalon or thru the caverns underneath the Plains of Dust.
This altered timeline starts after the War of Souls (Book 3)…The War of Souls.
The War of Souls begins in 421 AC, 38 years after the events of Dragons of Summer Flame. A small band of Knights of Neraka meet Mina, a mysterious woman who appeared during a freak storm. Through incredible feats, she convinces them to pledge themselves to “the One God” and follow her to march on the besieged city of Sanction.
Most of the native dragons are either dead or enslaved. The metallic dragons have disappeared. With the loss of the gods comes the loss of magic, and the Wizards’ Conclave had been disbanded years ago. Although sorcery, discovered by Palin Majere, was adopted, it is slowly fading for reasons unknown. Everyone, including the Dragon Overlords, experience the effect. The Knights of Takhisis, with the loss of their Queen, became the Knights of Neraka, a somewhat less honorable outfit than their predecessors, led by Lord of the Night Morham Targonne. Goldmoon, one of the few remaining Heroes of the Lance, has established the Citadel of Light on the island of Schallsea. In the elven realm of Qualinesti, Gilthas, the “puppet king”, rules only in title, while the nation is truly run by the occupying Knights of Neraka. Their cousins, the Silvanesti, have banished their heir, Silvanoshei, his mother, and his father. With the gods gone, the time period, fittingy, is known as the “Age of Mortals” as said by Fizban in chapter 32 (title: Rain. Autumn. Farewell.)
Over and over, Mina is able to convert her opponents and save the day. But at the city of Sanction, her plans >>Demil Plane of Despair accesses Absalon for the first time<< failed despite the valiant Solamnic Knights. Mina is captured and later killed in a ritual driven the black dragon Smolder, Strahd, and the Dark Powers, to destroy Tiamat’s latest incarnation.
Paladine, now mortal, takes on the name Valthonis is killed in the ill fated battle named the Fall of Haven. Some suspect Strahd was involved. Takhisis and Paladines death maintain the balance between Good and Evil. The good gods return to Krynn but the people have forsaken them, again. A sullen darkness has fallen on Krynn…
