-Galaxia is kinda like a cursed sword, but not necessarily a malevolent one. Those who aren't powerful enough to wield them either die trying or receive severe injuries. Those who can are basically required to because of the connection Galaxia forces on them almost instantly after they're proven worthy; it's not a soul bond but something very similar. Oftentimes the connection takes the form of a voice or voices in one's head, dreams, thoughts, or visions/hallucinations.
Galaxia themself is influenced by the one wielding them, which in turn influences the wielder. One who seeks power or battle may find themselves feeling somewhat more violent or ruthless, while someone with a strong will may be much more determined in battle situations.
As time has passed, Galaxia has begun to build up such traits, leading to them being somewhat conflicted sometimes; one side may want to spill blood, while another would rather play a defensive role, while another may want to avoid direct conflict if it isn't necessary. Some of those troubles may appear in their wielder.
-Sometimes aether magic makes a quiet humming sound when left undisturbed, so one of Magolor's first experiences with Lor was hearing that and it was unsettling for him.
-Spending time in Another Dimension often causes auditory hallucinations, like hearing faint music or voices– especially in places where dimensional borders are weak, or around portals
-On the subject of Halcandra, it is very different it is now than it used to be... Ask Nova what it was like and he'd tell you about the forests, deserts, lakes, mountains and plains, the hillside his creators often met on when visiting him. He'd mention the infrequent rainfall keeping things from being too lush but still being enough to support life there.
Ask Lor she'll describe the massive cities built around volcanoes, the lack of plant life, how you were either surrounded by rock, steel, or lava. When water came from the sky it was a miracle and a disaster; there was no rain, the infrequent times water came down was always in the form of microbursts that could possibly kill anyone unlucky enough to be caught in one.
-The majority of clockwork stars ended up developing some level of depression as they got older. Since they're basically still people(having a soul that belonged to someone else and all) but with social deprivation, it would make sense that many would be unhappy, lonely, & in some cases develop things like PTSD when seeing traumatic things. Nova, for example; having seen the most out of any clockwork star, including violent wars and people dying right in front of him, is an emotional wreck, because he doesn't have access to help or good coping mechanisms.
This is especially true for wish granters, as they're most often only treated with the utmost level of respect, without room for anything casual or emotional. It's probably emotionally exhausting for them, and any other clockwork star in the same situation of not getting much social contact.
