Plot
Spoilers follow.

Sayko and Crimna are siblings who live in the castle. Their abusive parents are The King and Queen. Crimna incites the plot by murdering them.

Crimna becomes king, and marries Irak, a priest and doctor who helped him plot the murders. Sayko is moved to live with CC, an elf in the forest. CC originally doesn't tell Sayko of her heritage, with her being a distant descendant of the royal line and technically a princess. Sayko discovers this and and begs her to return to the castle and help solve the problem with Crimna.

Meanwhile, Irak and Crimna are poor rulers and the kingdom is thrown into disarray. CC repeatedly refuses to return to the castle, due to bad memories of her time there. During that time, CC's sibling, Sargon, was heir to the throne. But Sargon refused, and pursued a relationship with the goddess Ezmira, who took a mortal form to be with Sargon.

CC and Sargon's parents did not approve of their relationship and banished Ezmira, and to retaliate, forged an alliance with a foreign warrior princess. This warrior was only using Sargon, and eventually murdered them. With her friend and sibling gone, CC fled the castle and swore to never return.

In the present, CC explains that Ezmira did all she could do to revive her lover. Ezmira cast a spell to revive Sargon, which resulted in ensuring Sargon's spirit would be reincarnated. Sargon reincarnated, into Crimna.

Sayko's alter, Adelmar, sneaks out of the house while CC is asleep. They go to the castle to investigate, and decide to murder Irak and Crimna. CC awakes to find Sayko's system gone, and panics. She finds what Adelmar has done.

Ezmira is distraught to have her lover's reincarnation dead once again. She uses a large chunk of her life force to revive both the kings.

Ending
Crimna and Irak decide to be better rulers. The castle is open to the rest of the cast, and relationships are slowly forged again, albeit not without problems.

Ezmira marries Irak and Crimna, and all three of them become rulers. Sayko becomes ruler of the elves, with CC assisting them.

Heir
