OOC:
The older posts are archived, but basically to give you the tl;dr, the group each had their personal reason to go to Barovia and met on the way there. Seeing they were all going to the same place, they decided to stick together. At an inn just before getting to Barovia, they were approach by a messenger pretending to cary a message from the burgomaster of Barovia who was looking for heroes to deal with an undead outbreak.
The party headed to Barovia and discovered the body of the actual messenger carrying a message from the burgomaster (in a different handwriting) asking that people condemn this valley and do not come to help them as they were preyed upon by a multi-centiry old vampire called Strahd who seemed to be obsessed with the burgomaster's daughter Ireena.
When the party arrived at the village of Barovia proper, they found there was indeed an undead outbreak (which resulted in some confusion as to what was the purpose of the "false letter" after all). Meeting the survior in the svillage square, they were told about Madam Eva and told to see her as her prophetic visions would tell the party what to do. They also hear rumor that the undead outbreak started at the local chapel of Serenrae.
The party went to visit Madam Eva, asking many questions about the undead, Strahd, the chapel, etc. They learnt that though the outbreak did started at the chapel, Strahd was behind it. They also learnt of 2 artefact which might hurt Strahd: The Sunsword and the Holy Symbol of Ravenkind.
Returning to Barovia, the party noticed they were often followed or observed by what they assumed to be minions of Strahd during the day, and attacked by said minions at night. Eventually they went to the chapel to end the outbreak in the village, killed Danovich the mad priest and his now blaspheme son Dory, and found the Danovich's journal.
The party then set out to find the artefacts to help them fight against Strahd. They already found the Holy Symbol of Ravenloft in a swamp where they fought a sea hag and some giant leeches for it. The party are now looking for the sunsword which was supposed to be hidden in some ruin in the forest, which also happened to be a den of werewolves. As they dealt with the werewolves they learnt of a new mysterious disease which makes people slowly waste away and seems to be beyond teh magical abilities of the people of the valley to cure.
And this is pretty much where we are...
