Character Details: 

Vespera was always a bright girl, studying every book and training from dusk to dawn. However, she was dealt an unfair hand in life, being born with the Eye of Rue (disability; more info in Discord). Her magic was severely weakened, and no amount of training could ever improve it. Scientists and medical professionals within the Sentinel Association came close to breakthroughs for a cure to the Eye of Rue. Still, Vespera had already given in to the siren calls of Augthorn. She felt like it was her only choice; she felt as if there were no other solutions. 

In the storyline, she is dating Bellamy Burnwind. She constantly feels like she’s living in his shadow, as he’s naturally talented and an adaptive learner, creating a contrast between the two lovers. Bellamy loves Vespera dearly and pays no mind to her weaknesses, constantly encouraging her. Vespera was secretly taking Augthorn (a magic-enhancing drug; more details in Discord), little by little. Once it was discovered by Bellamy, he begged her to stop. Due to the addictive nature of Augthorn, Vespera couldn’t get off of it and continued, leading Bellamy to turn her into the Justice Bureau of the Sentinals Association. 

Voice details, line context, and voice reference:

Vespara is a character with heavy baggage and is incredibly emotion-driven. She's frustrated and resentful in the series and often speaks with a tone of hidden hatred.

Line 1: She meets Lunette in battle and takes her down quickly. She laughs at her and sees her as weak.

line 2: She tries to relate herself to Lunette, but quickly escalates to setting a clear boundary between them. She should sound resentful and angry toward Lunette, belittling her.

line 3: This is a dialogue between her and Bellamy. She SCREAMS at him out of pure anger and she is saying everything she kept hidden for the past few years.
