Note: i am dm, party is level 3, leveld up to 4 at end of session

So my party was walking around castle ravenloft looking for the tome (it was foretold to be in the chapel) and they came upon the teleport room in the basement.

They collectively decided to use the red stone(lore) because they thought that would lead to the tome. Everyone except the ranger jumped in, teleporting up to the study.

The ranger in his infinite wisdom decided to wait for the hourglass to run out, and threw in the yellow stone and jump in. Now he’s at tsolenka pass...

The rest of the party goes back down and uses the green stone to vallaki.

While the party explores vallaki, the ranger goes onto the bridge, gets one-hit by the roc, but succeeds on his death saves.

Wtf do i do now????
