Trapping the Magus

A few minutes before the rising of the Undead army, in a different location.

The news of one of the Arcana borders breaking apart has long since traveled to the airs of the Berum Kingdom.

No longer being in a disadvantageous position, their army marched through the crumbles of the wall and pushed their blades dipper inside the heart of Arcana, 

Their aim is of the largest city named Canemacia which is known for hosting several magic academies which teaches thousands of young people to become magic caster or researchers and a mana crystal mine is being guarded inside the city. Which fulled the academy's needs of materials while also providing magic items to the city.

Though a mana crystal mine was considered dangerous if mined by an inexperienced person, Arcana being so focused on their magic had long ago figured out how to harvest them safely with less capable people.
