Character: Adriana in Throne and Liberty

In Throne and Liberty, Martinay's twin sister Adriana is a powerful shaman who was forced by the powers of Arkeum to perform a rain ritual, which was altered by the powers so that cursed rain poured down on Laslan.

Arkeum forces captured Martinay, the younger of two twin sisters. By keeping her hostage, they forced the shaman Adriana, who wielded the power of a Star Fragment, to call forth the rains.  

As the ritual began, rain cascaded from the sky, accompanied by crashes of thunder. But the Arkeum forces had altered the ritual. Their tampering caused a cursed rain to fall on Laslan.

Wherever the rain fell, creatures transformed into violent monsters that attacked people and devastated the farmland. 

Adriana was shocked to witness what she had done. When the Arkeum forces on the sisters, meaning to kill them now that they had served their purpose, the awe-inspiring power of the Star Fragment that lay dormant within Adriana flooded out, and their enemies were annihilated in an instant. 

In the aftermath, Adriana was beset by unspeakable disfigurations, swallowed by guilt over her role in causing the cursed rain.
