Wiki

In 2016, the Coal Hill defenders consulted a wiki page concerning East London to inquire as to whether Shoreditch's history with the Soers was at all documented. They found that the area was originally called the "Soers' Ditch", referencing the actual ditches the Soers had in a reality a few seconds out of sync with the human world. The website revealed that human abductions, always in groups of four or in pairs, were recorded as early as the 11th century, and that these often coincided with sightings of unusual green men.

April MacLean suggested editing the wiki page to include their discoveries about the Soers, whom they had just earlier drawn off the planet with threats of Shadow Proclamation intervention. The others decided this would not be for the best. Ram Singh believed that this edit, if carried forward, would be undone. (AUDIO: The Soers' Ditch)
