The Story of Syndra
Syndra's magic manifested young and violent — a telekinetic power so strong that it leveled her family's home before she understood what she was doing. In Ionia, this would normally be addressed by a teacher, by training, by the careful development of a student's gift within the traditions that had managed such things for generations. Instead, Syndra's village elder sent her away to a remote sanctuary tower, ostensibly for training, actually for containment. Away from everyone. Isolated.
She spent years in that tower believing she was being educated. When she discovered the truth — that she had been discarded, that the elder who sent her away was afraid of her and called her monstrous, that the "sanctuary" was a prison with prettier architecture — something broke, and something else was built from the pieces. She destroyed the tower. She destroyed the elder. She began pursuing her power not as something to be contained but as something to be maximized, because the people who wanted to contain it had demonstrated their motives.
Her philosophy is absolutist: power should be what it is, without apology or restraint, because restraint is imposed by fear and fear is other people's failure to deserve what you can do. She is not wrong that she was wronged. She is also pursuing power with a completeness that has consumed everything else — the joy she might have found in it, the relationships that might have grounded it, the context that might have given it meaning. She may be the most powerful mage in Ionia. The question of what power is for doesn't interest her anymore.
