Vesta

Vesta (ベスター) is a former minister of Dwargon and is currently the lead researcher of Tempest.

Appearance
Unusually for a dwarf, vesta is of a slender build, and rather tall, but around the height of a normal human.

Personality
After joining Tempest he has become more reliable. He got rid of that sharp personality and mellowed out.

vesta is an unexpectedly useful dwarf. Rather than politics, he is made for science. He was very boring when he was obsessed with political power.

Background
Vesta was the son of a marquis and second-in-command of Dwargon's engineering corps. He often argued with Kaijin, head of the engineering corps. At some point, the corps launched a magic-armor soldier project. Kaijin warned Vester that he was proceeding too quickly with the project, but his advice was ignored. A failed experiment grounded the project to a halt, and Vester put the blame on Kaijin. Kaijin took full responsibility and resigned from the corps.

Empowerment Arc
He requested Kaijin and co. to create 200 steel spears and 20 magisteel swords, fully aware that Kaijin will struggle with the order.

He later discovers the group at a nightclub and mocks Rimuru. This caused Kaijin to punch him, leading to the group's arrest. He bribed their lawyer to frame them, but Gazel Dwargo knew the truth and exiled them instead. After Rimuru and Kaijin's group left, Gazel expressed his disappointment at Vester's actions and stripped his title of minister.

Life in the Royal Capital Arc
He was brought to Tempest by Gazel to work under Rimuru. After apologizing profusely for his past actions, he was tasked with creating healing potions.

He and Gabiru are rather compatible. Because of that, he was allowed to reside in the Sealed Cave. The cave happened to be the perfect atmosphere for science experiments. Gabiru assigned two of his subordinates to guard Bester. Later, he joined with Ramiris in her labyrinth to conduct research.

Abilities
He has indulged in sorcery. However, according to Kaijin, he is not too good at it. Vesta is an excellent researcher and helps Tempest refine its process to produce its health potions on a large scale. He also helped to construct the magic circles used to travel around Tempest from the Sealed Cave (where Rimuru and Veldora met), to the Labarynth and to the city proper.

Relationships
