The Round Loaf was a location in Anglezarke Moor known to have great ties to the ancient Lord of Winter, Golgoth. Tom Ward often found Morgan, the Spook's old apprentice, searching the area.
It was said that Golgoth could be summoned from the Round Loaf by an individual who read from the grimoire. One winter, on the winter solstice, Morgan Hurst captured Tom Ward in order to use him as a sacrifice in the ceremony. After digging through the snow on that winter's day, they descended underground stairs and arrived in the chamber where Golgoth could be summoned.
As Tom watched, Morgan summoned Golgoth, but was killed as John Gregory had compromised the grimoire causing Golgoth to arrive within the pentacle. As Golgoth couldn't escape he threatened Tom to kill him and snuff out his soul if he refused to break the power of the pentacle. The longer Gogloth stayed there, the more his power waned. In the end Golgoth was forced to return back to the dark. (The Spook's Secret)
