Hellgate:Underground Stations

The first section of the London Underground was opened on January 10th, 1863. It was built from then on in great part by the Freemasons. While this provided a convenient and economical means of transport for the inhabitants of London, it also marked the fevered conclusion of the Templar scheme to protect the capital city of England.

John Fowler and Benjamin Baker, the chief engineers and designers of the London Underground, came from families deeply associated with the Freemasons. Every batch of cement used in the initial construction of the tube stations were personally inspected by one of them, ensuring that a very specific alchemical mixture was being used. The secret of this formula was passed along over the next century, allowing future generations of Templar and Freemasons to create a safe haven against the forces of Hell.

Covent Garden Station
The Covent Garden Station, which was one of the busiest on the Underground network, had no escalators - only lifts – which greatly slowed down the flow of passengers. It also made this a highly defensible location in many ways, and an early target of the demons. Obviously, the long-term plans to redevelop the station to cope with the increased customer capacity were never realized.
The station is most known for the stand the Templar took against the Demons in the early days of the conflict there. A particularly brutal assault, the same that caused a severing of the Tottenham Court line, came to its fearsome conclusion in the Covent Garden Station. The battle brought the most Templar losses to date, and it was only halted when they managed to push back the demonic hordes and then set off last-ditch explosives that caved-in the southern section of the station. Sealing off that portion of the Underground line, the blast crushed the majority of their enemies beneath tons of concrete and steel.
Although the Templar came away with a victory, it was a tainted one in that Covent Garden could never be used as a safe zone for establishing a community center. It still serves as a sketchy outpost, manned by a skeleton crew – more a listening post and waypoint than a means of transit or sanctuary. There are ways through the open tubes, but many potential routes into other parts of the city have been sealed with blast doors that are a part of the ongoing defense against the demons.
