Yggdrasil is a Swedish larp set in the universe of Harry Potter. The organisers has this to say:
The larp is set at the Nordic magic school Yggdrasil. During four days you will experience a magic world built on strong sense of belonging but also with threats and excitement where it’s tough to know who is friend or foe.
It’s a fantasy larp with neither very high or low demands on the players. It’s set in a school environment with possibilities for university level magic studies.
We’ve held one larp in the same campaign world before, in November 2012 which was very successful and now we’re trying again.
Where: Near Stockholm, Sweden. Participants will be transported from Stockholm by bus.
When: June 13-16, 2013
Cost: 500-700 SEK (approximately 60-85 Euro or 80-110 USD), not set yet. Price includes transport to and from the venue from Stockholm, food and lodging.
Language: The game will be played in Swedish
