But the portal was discovered first in modern times on the 22nd of January, 1509. It was located in an underground chamber by dwarven miners outside of Shirebrook who broke into an artificial chamber.
The dimensionalist wizard Georg discovered the activation and deactivation phrase for the portal and use it to obtain the Amulet of Malkis from the tower in the Shadow Plane. Georg then recommended the chamber be sealed up with the portal left inside.
In late December 1509, the mage Malakai was informed of the existence of the portal by Georg, and used it to travel to the Shadow Plane to save his friends who had ended up trapped in that plane.Hardcore Heroes Arcadia: Episode 5 However the portal was left open as the two spellcasters searched the Shadow Plane for Malakai's friends.
During this time the Demons who were also in the Shadow Plane detected and discovered the active portal. Soon the Demons used the portal to invade the 3rd Material Plane. This event is later known as the Demon Invasion of Eridon which killed at least 30% of the population of Eridon (~57,000 urban & ~215,000 rural) and put the whole world at risk due to the Demons growing a Demonic Colony in Heatstroke that feeds on soul and has started to grow to cover the land.
Days later, Malakai, Georg, Van-Healsing, Jeeves, & Lady Fanny Kougler arrive back at the portal and discovered it was being used by the demons. The group leave the Shadow Plane and return to the 3rd Material Plane then deactivate the portal, stopping more Demons from invading. Georg shrinks the size of the Stone Archway and the party take the portal to the ruins of Shirebrook.
The shrunken Stone Archway was discovered a long time afterwards in Shirebrook by a group of adventurers from Bergshire, Drekis. They gave the portal to Poorvan the nudist wizard in exchange for him to travel to Bergshire with them behalf of Desmond the Dashing.Shenanigans: Episode 159
