12 Ravenloft Realms, 12 quests:
Barovia: A dryad in Svalich woods punched a vampire through his chest, almost staking his heart. In retaliation the vampire severed the dryad's arm and then ran away, he probably died somewhere. The Dryad would like her arm back and is willing to give a reward.
Bluetspur: Welcome to the Dangerous Knowledge Quarantine District, citizen! You will be working alongside Grimlocks to transcribe and find applications for possibly cursed knowledge. This arcane lore could kill the entire illithid psionic network or any foolish mortals, so caution is mandatory. As you were listening to this message, knowledge of a simplified version of Qualith has been uploaded to your brain.
Borca: Ivana Boritsi has a acquired a list of Ivan Dilisnya's sleeper agents and needs them assassinated. These agents are animated toys who look and act just like real people. Nobody else knows or realizes these people are just toys, least of all the toys themselves. Show no mercy for these impersonators and Ivana might just find you interesting.
The Carnival: Redcaps have been soaking their caps in the viscera drawn from Professor Pacali's Hall of Horrors and are undergoing strange mutations. Eliminate them and the Carnival will go to any realm of Ravenloft that you desire.

Dementliu: No one wants to admit it but visitors have been disappearing from the Bonniville Museum of the Sea. Also, no one wants to admit that the new creatures on display are disturbingly familiar. On behalf of the Lord Governor could you figure out why that is?
Falkovnia: A rumor has been going around that Vladeska Drakov's birthday is coming up and everyone is making plans and gifts for the feared warlord. Either help Drakov stop this party from happening by executing people or join the secret planning committee.

Hazlan: Construction of a mobile stilt-legged refinery has finished in Sly-Var. The magical construct has to be escorted to The Brew where it will extract useful alchemical compounds. The route will be dangerous and non-magical mercenaries are being hired. Some apprentices have muttered that the refinery might have a mind of it's own...
I'Cath: The city is being invaded by Yatsukahagi (functionally Chitine from Volo's Guide to Monster) from another dark realm. Tsien Chiang's is annoyed at having to use her magic, Jiangshi, and wits to combat this threat while her great city still isn't finished. The spider-people believe a fugitive has fled from their realm and has taken shelter somewhere in the city.
Kalakeri: Help some Yuan-Ti purebloods escape Arijani and Reeva's clutches and get them back to Naga Island and their people. These snakeskins happen to have valuable information about Ramya's undead condition.
