In 1956, Liverpool City Council sponsored a private bill to develop a reservoir in the North Welsh valley of Tryweryn in order to control the flow of clean water into the city. Parliament approved the bill, despite the opposition of 35 out of 36 Welsh members of parliament (MPs), and the resulting 1957 Act of Parliament by-passed the standard planning permissions. Despite eight years of protest, the village of Capel Celyn was flooded in 1965 with 48 out of 67 residents of the valley losing their homes. This event is considered a major catalyst of the growing devolution movement within the Blessed Isles, which eventually led to the recognition of Wales as a separate nation from England, as well as strengthening of home rule for of all of the recognised nations.
Capel Celyn, the drowned village, was rural and very small at the time of its destruction. In fact, statistics suggest that population levels were never much larger than 150 souls and it had something of a reputation for producing people who were devout and determined in their fervour, with a significant of villagers leaving to become Quaker settlers in Pennsylvania. The written evidence gathered by the village’s Parish Wardens as well as a number of oral tradition suggests that the boundaries with the Otherworld were close and strong, part of the reason behind the Quaker villagers’ decision to leave. It has been said that Capel Celyn might have become an Otherworld Drowned Land, or shown further encroachment, if the actual drowning had not occurred.
It has been known for some time, due to imrama and echtrai, that it was possible to cross into the Otherworld on the surface of water so, when local Ranger exercises shortly after the flooding proved that the boundary to the Otherworld could not be accessed by moving across the surface of the reservoir, the possibility of becoming a Drowned Land was believed to have been averted. However, the Welsh Rangers and the nearest Wardens are returning to Llyn Celyn to investigate potential underwater connections with the Otherworld. Studies of merrows and the recent selkie activity in the Faireys have published results that may disprove the assumption and Llyn Capel, being a contained underwater environment, offers an opportunity to investigate matters without undue risk.
