The Dreadful Winter
When a Mistway fails to deliver travelers to the expected location, it is said to have drifted. Most Mistways have moderate reliability, drifting 30% of the time. Mistways with poor reliability drift 50% of the time, while exceedingly rare Mistways have excellent reliability, drifting 10% of the time.
When a Mistway drifts, it usually leads travelers to a random location in Ravenloft, though a handful of Mistways have a perplexing habit of consistently drifting to the same point. A Mistway can never overcome a darklord’s closed borders.
There are roughly twelve Charted Mistways in the region, and several still undiscovered.
