Modern :D

@Ryudo Prime In my series, individuals, known as Contractors, form a bond with a specific Sefirah (Tree of Life) or Qliphoth (Tree of Death). Each Sefirah and Qliphoth grants a unique ability, influenced by its corresponding angel or demon. The users of these abilities are divided into two groups: Elohim (Sefirah Contractors) and Gehenna (Qliphoth Contractors).

Should they be older than what they look like?

Older. For appearance, both of them should possess Human like figures with human features as a disguise but actually terrifying and something that should be perceive with their true body.

Something like Biblically Accurate Angel.

@Ryudo Prime The Contractors are Humans who have contracts with an angel or demon.

Yes and I am also talking about Angels and demons.
