BMWC 4 se konalo na jaře 2005 a náš slet tím uzavřel jeden cyklus ročních dob. Od této doby se již BMWC konalo méně často. Tento slet se konal na hradě Svojanov a programem připomínal spíše BMWC 2 – tedy výlety do okolí. Konalo se zde několik málo workshopů, mimo jiné zaměřených na léčení a na tarot.
BMWC for was held in spring of 2005 and it closed a circle of the four seasons. Since then, BMWCs have been less frequent. This conference took place at the Svojanov castle and it was quite similar to BMWC 2 – it consisted mainly of trips to nature. There were only few workshops aimed at healing and tarot.
