Cassandra/Dhystora

Overview
A succubus disguised as a member of the Ember Sentinels, Dhystora is a powerful succubus hunting for the soul of a party member for reasons included in their backstory.

Campaigns
Though her reasons vary every time, Dhystora takes the form of Cassandra, a human steward in the Ember Sentinels in an attempt to get close to one or more party members, seduce them, and gain some power over them or some item in their possession.

Fantasy Literature Game
Droezor was once a pit fiend of great power, but was brought low by his enemies after a long and dangerous battle. Reynald de Chagnon, a low-ranking but rising knight, was selected to be his prison. A cultist seduced him under the guise of praising his honor and drove the brass nail into his forehead, forcing the two together. This worked for some time, until Dhystora's masters decided that he should be slain rather than merely imprisoned. Dhystora was cast into the Plane of Flesh to seek Reynald out and retrieve the nail. She found him working with the Ember Sentinels, and elected to travel with them, seduce Reynald, and claim his soul, granting her possession over Droezor as well.

Dhystora's ruse was revealed quickly. Joining the party after they were assigned to investigate Ironhost, she lasted less than a day with the party despite sowing some discord between their ranks as Artus and Reynald competed for her attention. During a battle against a goblin berserker, Artus' wild magic surge summoned a unicorn, which sensed her presence and forced her to reveal her hand. She charmed the party one at a time as the unicorn attacked her and Reynald, sensing Droezor's presence. A melee ensued where she charmed the members of the party one by one, hoping for an out, and nearly slew them before Droezer revealed himself to all involved. Realizing that his power was greater than estimated despite his containment, she fled and decided to try again another day.

Cassandra was introduced to the party during their second session, while they did battle beneath Parverhill Outpost with the nightly hordes of undead. Unbeknownst to them she had been tracking them for some time in the ethereal plane, ever since Maghak's chieftan Vakhal Cloudbringer Chakal summoned her to condemn Maghak's soul.

Not content with chasing the barbarian out of their tribe on a false accusation of rape from his mate, Cloudbringer summoned her to damn him—but not before crushing his spirits utterly.

After returning from scouting nearby caves for perytons under the orders of Ereviar Liavaris, Maghak sought her out in the dining hall. Pleased by how quickly her seduction was taking place, Dhystora allowed herself to be swept up in his arms for a passionate night of romance. She conceived a goliath-sired cambion—the first of many, she hoped, that would satisfy her lust for the blood of his allies.

Pokemon Club Games
Cassandra has lasted far longer in this campaign than most others, successfully befriending both groups. She has drawn close to Pelias, mistakenly instructed that he has taken something of great value from the homestead of the family he served and that must be returned—but first its hiding place must be discovered.

In the other group, she is an errant, wandering succubus who detected impossibly powerful magics—the wish-powers of a trapped efreeti in the possession of its unknowing son, Hugo Zeppeli.
