Content Warning: This section of the guide includes discussion of graphic violence, death, emotional abuse, physical abuse, and sexual violence.

Dianna, the protagonist, is an Ig’Morruthen who is over 1,000 years old and who typically resides in her human form. She is statuesque and strikingly beautiful in this form, with long, curly, black hair and hazel eyes. However, Dianna can shapeshift into any form, favoring the wyvern—a powerful and mythical beast.

Long ago, Dianna was a mortal on the planet Eoria. Her life changed irreparably when Rashearim fell, as shards from the shattered planet caused a devastating plague that claimed her parents and would have killed her younger sister, Gabby, if Kaden had not intervened. Kaden saved both sisters by turning them into Ig’Morruthens, immortal beings with extraordinary abilities. In exchange, Dianna became bound to Kaden as an indentured servant. Through this transformation, Dianna gained incredible powers, including immortality, superhuman strength, shape-shifting, rapid regeneration, and reading memories from blood. However, she deliberately limits her abilities by avoiding mortal blood—a self-imposed constraint that reflects her inner conflict.

Dianna’s character is defined primarily by her unwavering love and devotion to her sister. She sacrifices her own freedom for Gabby’s safety, continuing to serve Kaden out of fear of what he might do to her sister if she disobeyed.
