Desyyla's dad and mom have been part of a historic organization that makes use of specialised ancient technology.
Her mom desired Desyyla to be the next prodigy to their race, as they had been suffering super losses because of the cataclysmic warfare.
So, she was brought right into a room that holds a large set of crystal stones that emit magic by means of shining light.
the whole thing was going as planned, but suddenly she begins to experience a bit funny as she begins to increase in size, but at a brief rate.
Her mother and father were flabbergasted with what they're seeing, as their own daughter's size grew exponentially, her head and frame burst out of the pinnacle.
unluckily, this prompted some structural harm to the foundation, and her parents have been overwhelmed by the big chunks of the building falling onto them as they try to stop the growing process.
It worked, but as she grew back down to her ordinary size, she reveals everything absolutely destroyed, and her mother and father nowhere to be determined.
As she ponders over this, the enemy was bursting in thru the halls, now on the hunt.
She decides to use these powers for all that is right, and she grows, the others alerting to her presence.
She effortlessly crushed them and destroyed their armies, because of her giantess size.
She fought long and tough, and this spanned for quite a decade, likely spanning over before she was finally put down.

Years later passed...
Desyyla's emotions cooled down, and she has turn out to be quite a protective guardian, the use of her size converting capabilities to her benefit in battles.
