The day before Ravenfell was attacked, Marden had gathered all the Mana Core Magi who would be participating in the upcoming battle. This meeting took place right after he had finished speaking with Taron Norwood and Daniel Ranzenberg.
Somewhere in the snowy mountain range, north of Ravenfell, seven people—including Marden—had gathered in an abandoned outpost. They all radiated vast, overbearing auras, their strength capable of dividing the clouds and rendering the lands.
Scattered across the mountain range were several outposts, each positioned at key strategic points. In the distant past, the Magi of Ravenfell had built and used these fortresses during a brutal war against a terrifying species of magical creatures that once ruled these peaks.
