The Collector peered at the decapitated head in one of its arms with mild interest, its four glowing red eyes flickering as they scanned and analyzed, green magical energy enveloping them.
Haze.
This was what the Collector found from its mana scanning. The flow of mana from the specimen itself was clear, almost unnaturally clear.
All living specimens' bodies formed a natural dampener for the expression of their magical energy. Their skin and flesh encased their hearts, their core, and flowed mana within them, and thus insulated them from outward observation somewhat.
This was part of the principle of why it was difficult to directly affect an individual's mana core from within. The rest of the body formed a protective barrier.
However, this 'Undead' specimen flared out its magical energy constantly and with such clarity that it almost seemed as if it was just a walking core, lacking any dampening inherent to every magic capable living being.
