No one knows how long Svarta Sanningar have existed. The first known observations of the society were in the 1970s, on a small island Tuve of Hisingen, just outside of Gothenburg, Sweden. The only official documentation is a surveillance tape, recorded at midnight on the 11th February 1976. From the recording there is hard evidence about a land deal that went wrong.
PBCL Investments (the deal contractor) leased the land to Svarta Sanningar for a multi billion dollar sum for mining metals. Once the deal went through, the whole area was in the locked down and no third parties were allowed to enter.
Under mysterious circumstances, the dead body of the CEO from PBCL was found in his office the following week. The police declared it as a ritual suicide and the case was dropped.
Furthermore, there were also unconfirmed testimonies about occult fairs in the Tuve area as well as frequent nightly helicopter activities in the airspace around Tuve during the period of 1976-77. The helicopters were black without markings. A retired general from the Swedish air force, later active as a church pastor in the area, Ernst Mörck, confirmed that it was the same helicopter model used by the Swedish Air Force at the time.
The following year on the 30th of November, a severe landslide took place in the area of Tuve, later called Tuveraset. The official explanation of the tragedy was that it was intense autumn rains that had created a highwater pressure in the ground, thus impairing ground stability.
A military investigation showed several indications pointing to a shady deal reeking of corruption within PBCL Investments and the residents in the Tuve area. Still to this day, what actually happened that day are shrouded in secrecy.
