Ylva
Föreningen Ylva is one of Swedens oldest game clubs, founded in Göteborg in 1986. Allthough being no larp organization, it was the organization from which an interest in larp was formed in Sweden, and out of which Särimners Vänner was formed. Ylva was also the organization which built Kellys Hjältar diorama role playing game, which has been an influence to the Swedish milsim form of larp.
