Riala

A very powerful succubus, she has not only a body that can kill, but is also a highly skilled mage and strategist... and wants Simon in her bed. Her age is something of an unusual status among succubi.

Story
Very little is known about her origins but her unusually advanced age and her extraordinary knowledge in both theoretical and practical magic confirm that her formative years preclude the apparition of the actual Incubus King in Arclent. What is known however is that she is the catalyst that started the events that will change Arclent forever. She is the one who implanted the Soul Shard into Simon.

During the failed assault on the Withered Mountain Fortress she confesses that she has been after Simon both sexually and emotionally for some time. Riala's reasons for turning Simon into one of the soul shard bearers is because she wants him to overthrow The Incubus King. As she considers The Incubus King to be a complete idiot with too much power for anyone's good and is fed up with the bizarre tasks she's constantly given, such as finding a giant chess set made of fecal matter.

She shows a fondness for Robin whose innate talents remind Riala of herself when she was younger and as such offers her a tutorship when and if time and circumstances will permit it.

Sadly, Simon's actions in nullifying the power of the second crystal sent by Iris has not only split the party in various groups and planted Simon in the greedy hands of The Empress, but also has alerted the jealous and suspicious side of The Incubus King and he has forced her to come to his side and receive punishment. During the Gathering, Yarra has the chance to learn that she is now serving him meekly after her punishment.

During the war, Riala reveals that she hid a portion of herself as deep as she could into her subconscious to be protected from The Incubus Emperor, that which remained being subservient to him. Only the events of the Third Arclent War allow the group to confront and capture her. The shared intimacy with Simon restores her conscious mind, but the damage The Incubus King did has left her considerably weaker than before and she needs time to recover.

The end of chapter 3 reveals the source of her extended lifespan, something that could be called an anti-shard that has similar properties to the soul shard that she gave to Simon. She can use her sexual powers to drink from this shard and it has extended her lifespan, but it gives diminishing returns the more she has used it. It also subtly tries to compel her to absorb it, which she theorizes would grant her immortality similar to an Incubus King, but held back due to the power it would grant her not being enough to defeat The Incubus King, who would know had she absorbed it and investigate.

It's also revealed where she discovered the two shards, a place she calls "metaphysically complex" after attempting to bring Simon there, but only partially succeeding due to a lack of power.

Tactics
Riala is an unholy combat fusion of Robin and Yarra, combining their strengths of single target and AoE spells, sustainability and disables to make a very strong party member. The versatility of her spells allows her to choose whether or not to mix arcane and sexual for optimal damage, as well as providing various status effects. Of course she also shares Robin and Yarra's weakness of being squishy in combat so you should have a dedicated healer on hand to keep her healthy.
