Lynine

Elder Lynine is an elven mage from Darghelon with an enthusiastic interest in succubi and corruption magic, something very unusual for the forest kingdoms. It stems from her belief that focusing on "purity" has made elves more susceptible to the Incubus King's powers and that the enemy's tools can be used against him. Her interest seems to be more than purely pragmatic, though - she even dresses like a succubus, much to Yarra's delight.

Lynine's views has put her at odds with Orilise, a scholar from Gheldaron comparable in status and influence.

Story
You meet both Lynine and Orilise during your first visit to the elven kingdoms in Chapter 3, after the Incubus King Emperor has had a seed of corruption dropped on both their queens while they were negotiating. An elven diplomat asks the Doom(ed) King for help, so his most trusted commander is sent to deal with the situation.

Lynine and Orilise are seen on a bridge, bickering and blocking each other's efforts to help the trapped queens. After that, Simon's group has the chance to meet them separately and hear each one's side of the argument. Lynine is fascinated by the succubi, who in turn approve of her clothing. She makes it clear that although she has embraced sexual magic, she understands perfectly well what the Incubus King would do to her. In contrast, she's enthusiastic about what she has heard about the Doom King and wonders if he would accept an elven volunteer.

Both Orilise and Lynine offer to help Simon's group in procuring materials for a spell that can remove the corruption from the elven queens, and the player has to choose whose help to accept. As of version 0.20, the consequences of the choice are unclear, though it's implied that it will have political implications later on. Sierra Lee has stated that the player will have to make a more significant choice between Orilise and Lynine later in the game.
