Obv she is
Lilliana obv can't give birth to a descendant of elf queen as she's a witch
And from the start they were showing Liliana brainwashing or something to keep the king to her chambers
She maybe kidnapped the empress daughter to keep the empress spirit powers in low cuz if she had a daughter and she herself and her son all three would have made a quite strong team
Or maybe she needed a sacrifice from the first elf queen's descendants so she kidnapped
Y'all why do I get a feeling that's she's actually the empress's daughter
