Celestia's armor

Summery
the armor was forged thousands of years ago by both Celestia and Luna's parents to contain the immense power the former radiates. throughout her life, Celestia has been told to never take off the armor, to ensure the surroundings don't get burned or destroyed. Celestia finally uses the armor's hidden function to battle The Shadow and wins. the armor is destroyed, but it is no longer needed as Celestia has learned to channel her power without side effects.

Abilities

 * Power Absorption: the armor's main function is to absorb and contain the energy that Celestia radiates. the armor can only absorb the power of the one wearing it and can't absorb external energy.
 * Power Channeling: a hidden function of the armor allows it to empower the one wearing it with the energy it has absorbed. this also destroys the armor from the seer might of the energy being released.
 * Shapeshifting: the armor was designed to grow and shift according to the user's needs and can even turn into nightwear for sleeping.

Users

 * Celestia: wearing the armor from birth, Celestia has been the only user of this armor.
