Ariessyss, Succubus of the UnderRealm

Before the first Clash of the Realms, before she was banished, before she became Achlys, she was Ariessyss. When she first popped into the UnderRealm she was confused and terrified, but not too long after Lucy found her and helped her calm down, then then explained everything to her. Even though she was still scared she at least felt reassured and comforted by Lucy. Wen Lucy asked what her name was she couldn't remember, so Lucy gave her a name: Ariessyss, after Aries because of her horns kinda looking like a Ram's. Over the centuries they became best friends and always doing everything together, like playing games on each other or getting them into trouble. She loved being a mischievous troublemaker and sneaking into where she wasn't allowed, but later on because of that, Lucy's dad though she was a bad influence and decided to separate them. Confused and heartbroken, she then started to have a parasocial obsession with Lucy, trying everything she could to try to see her again, but she always failed. This only made her hate authority and being controlled, and made bitter inside that would build up over the centuries, but she would hide it from everyone else because she knew there was nothing she could do. This would change one day when she found a glowing purple gem when she was wandering through an old battlefield, she thought it was pretty, so she took it and turned it into a necklace. What she didn't realize is that it was slowly corrupting her and intensifying her thoughts and emotions until a reached a breaking point, at that point she tried to overthrow King Lucifer. She was able to beat some of the guards but was quickly overwhelmed and restrained. She was brought before the king in chains and all she could do was growl towards him, but when she saw Lucy standing next to him and saw the look of fear on her face, the romanticized fantasies she had been obsessing over for centuries instantly shattered. With this, the last bit of herself was gone, now replaced with an even greater heartbroken husk who swore revenge on everyone who's ever wronged her.
