Angelic Buster has GOT to be one of my favorite characters, because she has so much potential. I wished there was more thought put into her and her character, so I put it there myself! It's both a redesign and a class rework, focusing on both sides of the pirate class- her true form uses fists, augmented by Eska's power, and her short lived transformations use the standard soul shooter!
Her design is based off of Korean dragons- Redesigns of Nova NPCs are below, showing how she deviates from the standard European.
The largest change to her story is that Eskalade is no longer a creepy old dragon man that has a huge power imbalance with Tear, but is now a dragon goddess that's... just a kid. 13 years ago, the Novan Diety, Eskalade, reincarnated for a fresh start, sealing themself inside of a relic so they would be safe from the outside world while they relearn and remature- but not before starting a rumor that the relics were cursed. This 13 year old with the powers of a god views the Novan people as a lot like toys, dolls to play with. Tear is her personal favorite, and she always daydreamed of her being her older sister. So, when Tear became bound to the relic, she was OBVIOUSLY elated. Their relationship is actually friendly and mutually beneficial in this retelling.
The Nova classes are still missing a Mage, and I think that this would be the perfect opportunity to do something with Velderoth's character: making him the mage class.
Hear me out here. Both Kaiser and Tear, the two members of the Heliseum Force, have classes of their own. And I know Velderoth turning to Magnus for power made him a boss monster rather than a candidate for a playable character (or even an NPC, for some reason). HOWEVER. This does not mean that we can't provide Velderoth with a more in-depth reason for joining Magnus, something that demonstrates his commitment to his friends above all else.
I'd like to put forth the idea that Velderoth is working undercover.
In this idea (for Velderoth being the Nova Mage class), after storming off from the Heliseum Force Hideout, Velderoth was confronted by Beldar on his way to Heliseum. Fenelle had prophesied that Velderoth would turn traitor to the Nova people if left to his own devices, so to mitigate this, Beldar, along with Cartalion, decided to recruit Velderoth for a special mission. Since Velderoth had the strongest connection with Kaiser, he would undoubtedly be seen as an asset to Magnus. Therefore, it would be up to Velderoth to weaken Magnus's forces from the inside.
Since it would be too noticeable for Specters' numbers to suddenly decrease or for them to be physically injured, they would need to be drained of their power to a certain degree. To do this would require a powerful Magician. Beldar recognized that Velderoth was powerful enough to cast such spells - he simply needed training in magic first. Cartalion explained to Velderoth that no other member of the Nova army would agree to such a mission, especially since the consequences of failure were beyond dire, and that he knew what Velderoth was capable of from his training as a knight. Velderoth, feeling empowered, agreed to become a Magician and work undercover to help the Nova people - especially his friends.
As we all know, Magnus took Velderoth in and used him as the third Guardian of Heliseum, and eventually Kaiser and Velderoth had a battle. However, the Velderoth that Kaiser fought against was an illusion created by the real Velderoth, hence why he was seen escaping Heliseum. Once the illusion fell and Magnus believed him dead, Velderoth went to a location specified by Beldar and Cartalion, where he remained until Magnus was defeated and Heliseum was successfully reclaimed. After Kaiser's victory against Magnus, Cartalion and Beldar made sure that Velderoth would be safe to return to Pantheon.
Kaiser and Angelic Buster had a rather tearful reunion with Velderoth once he came back to Pantheon and explained everything to them (this is also the class storyline where Kaiser and Velderoth find out that Angelic Buster is Tear). Velderoth confessed that he had been jealous of Kaiser's power, but he was also afraid that the people he cared about most would be lost to him forever after the incident at the southern border of Pantheon, feeling, for the first time, the weight of their mortality. Now, though, he recognized that all of them were powerful, with different skillsets, and they could overcome anything together. There was no reason to fear anymore.
(Sidenote but I feel like they should all fight together against the Black Mage. All of the Nova classes. I think that'd be really neat!)
