Ornelia, The Sun Eater (Viricia Sol-Hadul)

Viricia Sol-Hadul entered an unforgiving world far too early. Desperate to save her doomed pregnancy, her mother, Alduri Sol, turned to a higher power, determined to save the last remnant of her slain lover. But some prices aren't worth paying, and Viricia shouldered the cost. Her body became a host for a Godspawn, a trans-dimensional parasite acting as a conduit between planes for those with the might to use it. From the day of her birth, existence became agony. Had her mother not been a powerful sziira, she might not have survived at all, but fortune was not in her favor. Her body strained under the weight of insurmountable forces beyond her control.
By luck or sheer force of will, she continued to survive. When her mother's patron offered her a deal to be free of her pain, she accepted in an instant. She would merge her consciousness with that of the worm-like Godspawn inhabiting her, and in doing so, she would become a living weapon.
