- “For an Akiridion, as long as your core remains intact, then you can survive almost anything. It is our very soul, and you must nourish it. Like a spark, it can be extinguished, or it can be fanned until it burns bright.”
- ―King Fialkov to his children, Aja and Krel, about an Akiridion's core during a flashback[src]
Life Cores are the souls and life forces of Akiridions.
Life cores come in various shapes but they're typically long and rectangular in a translucent blue color. The royal life courses have a unique design. The life core of the rogue Taylon Phalanx soldier whom General Morando killed was a bright red.
The cores are the center of an Akiridion's entire self, defining their molecular structure and allowing them to exist. Even if an Akiridion's energy body is destroyed, they can survive for as long as their cores are safe and their bodies can be reformed after a long process of reconstruction.
Life cores cannot be regenerated once they've turned dead gray or if they have been crushed.
- The only other life cores seen in the series are the ones of Vex's deceased family, Vex's own core and many other dead life cores. One of Morando's soldier's life core is also seen before he destroys it, killing his own soldier.
