Pathfinder: Saga of Fate/Calamity

Calamity is a samsaran blight druid who uses a twisted form of druidic magic to hinder her foes.

Backstory
Calamity knows nothing of the circumstances of her birth. She was left on the doorstep of an orphanage in Kyonin with no given name.

What sets samsarans apart from other races is that they are not born. Instead, whenever a samsaran dies, a new incarnation is created in its place, possessing vague memories from their past incarnation. However, Calamity is a unique case in that her past incarnations all died violent, gruesome deaths, and that the moments leading up to said deaths were the only memories she could recall.

Growing up in the orphanage, it was made very clear that Calamity was a very disturbed child, which was mostly due to these destructive memories. She would partake in such destructive behaviors as lighting objects on fire, crushing insects and small animals with rocks, ripping apart flowers, and tearing the wings off of butterflies.

When Calamity turned 33 (human equivalent of about 8), word of her disturbing memories had found its way out of the orphanage. Soon after, a strange man came to the orphanage and adopted Calamity.

The man revealed himself to be the member of the cult of Ghlaunder, the Gossamer King. The cult thought that Calamity and her destructive memories would make for a valuable addition to their organization, which was obsessed with the eventual destruction and decay of all life.

The cult trained her in the ways of the blight druid, who use a twisted form of druid magic that centers on the natural death and decay of living things. They also gave her the name Calamity, due to her obsession for the cataclysmic.

Calamity trained with the cult for 27 years until she was 60 years old. Even though she had spent a lot of time with the organization, she had no love for the murderous cult that raised her and trained her. Though the concept of destruction interested her, she had no intention of committing mass murder as Ghlaunder's cult did.

When the time for a special ritual in which a chosen member of the cult would have their heart blood feasted upon by the Gossamer King himself, Calamity was the one selected. The cult's plan was to sacrifice Calamity and recruit her reincarnation, which they would also sacrifice when the time came, creating a continuous cycle of sacrifice and rebirth to please their king.
