Orchidna

Orchidna was a child, the bastard sister of Kyprosa Daeior's father, Prince Raeven Daeior. He had been obsessed with the Akasch and was exiled by his mother, Rosia. Years after he was exiled a baby was delivered to the doorsteps of Fir Castle and the letter announced to Rosia, that this was his daughter, Orchidna. She had a strange, otherworldly appearance, and eyes that knew too much for one so young. Even when she was an infant, people shied away from Orchidna. On top of being the bastard child of an exiled prince, she was wild. Unpredictable. Kyprosa raised her like a mother and provided some counterweight to the wild instincts of Orchidna. But still ... as she grew older, she gained terrifying powers that no normal magic could explain.

Lucius Quinto believes she is not just Raeven's daughter but that Akasch blood flows into her veins as well!

She was a member of the original expedition. When the 12 found the gate to The Garden in the depths of Auroria she opened the gate and was bound to the throne that sits opposite to it, replacing the fae that was seated there before and releasing the faeries into the world. A deal was struck by her father making her the new queen of creatures from another dimension (today known as Warborn). It is assumed that this is the reason why she was pulled to the throne when she came near it.

The other members of the expedition left her there, promising to come back with magic that could free her. It is unclear what became of Orchidna in the centuries since then, but there are hints that she is far from being an innocent child by now...

Whilst she was on the throne she made the Warborn. With them it's assumed she orchestrated the Ezna massacre. When she became dormant, her guardian son Damian freed the Warborn from her and the Akasch influence.
