Some lore info for those still at work, but wanting to know more
Basic Event Background:
"When the Circle of Thorns secretly began linking their magical energy in an effort to make them more powerful, experimenting with ways to extract the power from other magical groups, they inadvertently put into play an event that would change the magical landscape forever. During a series of incantations, with the use of extensive symbols and magical rites, they formed Banners that could summon the 'aspect' of nearly any entity, alive or dead, to be used as a mindless slave in any way the Circle wished. While they could not actually summon the true entity, a piece was certainly enough for their purposes.
At first, they were delighted with their success, imagining a multitude of uses for this new type of slave: more bodies to use as an army, return fallen Thorns to battle, use the entities of other groups as assassins: the possibilities were endless. Unfortunately, the ritual on All Hallows Eve didn't go as planned. The Banners they summoned behaved independently of the Circle's will, summoning Defenders who would not to obey their commands. Worse, they discovered that while these 'haunted' Banners were active, Glyphs appeared one after another, making it more and more difficult to banish them and that as the closer they came to the Banner, their once nearly infinite well of power reversed on itself and made them weaker. They disappeared into the night, leaving the mess for others to clean up, not realizing that an even greater threat had manifested itself.
