'''Mare Incognitum''' was a lovecraftian mythos horror larp set in Norway in 1951, and played onboard the destroyer '''HMS Småland'''. The larp had 26 pre-written characters from different groups. Three games were run over the course of a weekend, and had participants from Sweden, Finland, Norway, Denmark, Estonia, Spain, the US and the UK. The game was organized by [[Berättelsefrämjandet]], and had some ten NPCs and crew.
