The One Without Sin was written in 2017 by Rosalind Göthberg, Siri Sandquist and Alma Elofsson Edgar in Swedish, as Den Utan Synd. It ran once in 2018 and once in 2019, the second run also welcoming Danish and Norwegian speakers.

The 2026 international run is adapted and organised by Rosalind Göthberg, Siri Sandquist, Alma Elofsson Edgar and Mimmi Lundkvist, through the organisation Bread and Games. 
The organisers have previously made historical larps (some together with each other, some with other organisers) like:
Snapphaneland (Swedish/Danish, 2022 and 2024, Bread and Games)
1912 (one Swedish run, one international run, 2019, Atropos)
1913 (Swedish/Danish/Norwegian/Finnish, 2025, Atropos)
Stenrike (Swedish, 2022 and 2024, Bread and Games)
Trohetslöften (Swedish, 2025, Bread and Games)

The One Without Sin can only be run because we have help from the following people:

Kalle Lantz and Frida Selvén, who took the photographs on the webpage 
Eva Wei Markehed, who does financial logistics
Bunni Fishwick-Ford, who proofreads all the texts
Kim Bjurström and Karin Källström, who are in charge of food and kitchen helpers 

Thank you!
