Hazlan is in walking distance from Barovia.
Well it would be like a ship to Blaustien except it would go from Dementlieu port to the closest target to Barovia. I was told that Hazlan would be the closest. If not then what would be the closest and would it even be possible?
Barovia is almost in the middle of the same continent as Dementlieu. Hazlan is southeast of Barovia, whilst Dementlieu is northwest. So, these domains are in exact opposite directions from Barovia.
I suppose Luna River might be navigable, though, albeit I doubt it's a good idea to sail it through Verbrek in order to get to Hazlan. And in any case, I don't think it would be a beneficial add, taken into account 1) the distance and the IC problems that brings 2) the purpose of having Mist camp as a hub.
Here's a map of the
Core.
