In Vampire the Masquerade, which is what this game is heavily influenced by, the first vampire was Cain (the one from the bible cursed by God). Because of said curse, he became the first generation of vampire. He then turned 3 individuals into vampires, where they adopted a large chunk of disciplines (powers) that were taught to Cain by Lilith, who learned these powers from Satan. The 3 individuals became the second generation of vampires. They then turned a chunk of individuals into vampires, passing along certain disciplines onto each of their children. These children were the third generation of vampires known as Antediluvian's. After said Antediluvian's killed the second generation, they embraced a few people, creating 4th gens known as methuselahs. Essentially, 3rd gens are antediluvians, 4th and 5th gens are methuselahs, 6th-8th gens are elders, 9th-13th gens are ancilae, and 14th-15th gens are thin bloods. Also, the lower generation a vampire is, the more potent their blood is due to being closer to Cain, and depending on the generation of one's sire would determine how fast they can learn disciplines as well as how many they can start with. Since mc is exhibiting extremely high lvls of powers while only being a vampire for a short period of time, it's safe to assume his sire was around 4th to 6th gen, which would allow for him to be a methuselah or elder and be able to obtain more disciplines faster.
