A Different Perspective
The Solar students didn't have a council. Denying anyone a voice was against the values of the society that they had created.
There was no reason for it. The Solar students had certainly had different arrangements, a council once upon a time, a parliamentary situation, a monarch for a while... they liked experimenting with things. Change came far more easily for them.
Sometimes too easily.
The Solar students had all had mixed feelings when the stone had informed them that they were so. By the time they had gone from their gardens to the magical room of inner essence they could already pick up a few things about what it would mean if they were a Solar student. And if they didn't before they had been so designated, they certainly would find out afterwards.
Being a Solar student was terrifying. Because members of your harem, your protectors and followers and best friends, they could die.
Lunar students could grow. Change. They were susceptible to the magic of different territories and regions, one large region being the closest to "fatal" as Lunar students could get.
But they could live through anything. And most of their powers involved effects that, while casual to the Lunar population, would often kill a Solar student immediately.
Some students responded like Hermione did - devoting themselves to the study of why they had been made here, in this world where they didn't seem to belong, trying to divine its true nature and maybe have a chance of changing the rules of it all. Some responded like Buffy, training as hard as they could to be capable of their best in pursuit of making a difference in justice outside the bubble. Some responded like Elena, giving up completely on a life outside of the Solar and common grounds of the Academy and trying to make the most of the life they had as what they were, making everything about their team and trying to see those beloved people as happy and fulfilled as they could be without pushing the limits or putting them in danger.
They weren't nearly as worried about the new member of their society. Which is why they were currently harboring him and his followers within their region of the Academy until the Lunar Council could come to a consensus and convince their student population to not kill him as hard as they possibly could and/or throw him out of the bubble with a speed and ferocity that could only be described as "yeet".
The Solar students DID have many feelings about that. The harboring, that was.
These were succubi. So? We have vampires, and werewolves, and other such things, many of which function in quite the same was as these succubi seem to. These were mages. So? We have tons of witches, and an entire harem of wizards, that's nothing new.
But although words could easily argue against the pure logic, it couldn't move the emotions of a large population of Solar students. Because those words missed the point. The point was a matter of scale.
Maybe it was just what they could survive. Maybe it wasn't just how many they could kill. But until these new people tried, we wouldn't know. Were these the kind of mages that practiced little magics like we could? Or will they create a fireball the size of a bedroom around them every time they're upset?
There was a lot to talk about.
Annabeth gave a speech about the importance of inclusion, with Katniss backing her up. Both had small but tight groups with an exceptional amount of ability. The rebuttal to that speech was mostly focused on how Annabeth couldn't possibly begin to understand the fears of the rest of the populace, with her and her harem's powers being so Lunar in scale and nature.
Feyre followed with a speech about the importance of caution, citing the universally heard of experience she had suffered with a member of her own harem, now rightfully locked up in perpetuity, showing a complete inability and unwillingness to grow. She referenced Elena's similar experience with members of her once incredibly large harem now gone or in similar isolation and captivity. Elena was invited to give a talk supporting or negating Feyre's use of her experience as comparison. She refused to do either.
Bella left early. This was expected. The woman easily tired of attention, and her Harem boasted some of the most terrifyingly powerful beings in the Solar populace other than Elena, and thus was getting a lot of questions as to her opinions on the potentially-dangerous and un-leashed concept of this new guy. But also. She needed tending to by her little Harem almost constantly. She and two in particular of her harem made rabbits look chaste. So the Solar discussions made due without her.
The talks went on long into the night, but in the end the man and his harem were given a room, with one member in particular given a bed in the section for "platonic followers". The Solar population was torn on even using the term "harem" for their groups, as it was so much more common than in the lunar populations for a sibling to spawn and need a place to live separate from the "harem" proper and its - ahem - needs for power recharging and mood regulation.
They were hardly going to put a Lunar Man and his daughter in the same bedroom, even if they were disturbingly comfortable with rooming together for the night. They didn't understand yet what their existence in this world, ah, required, so the statement could be forgiven as ignorant appreciation of hospitality, but it still was uncomfortable for the rest of the population to hear.
For now, the situation of this man's protection had been secured.
But what the heck was their society going to do about this in the long term?
