This takes place in the far future after there have been multiple cycles of hedonistic societal collapses.
The main reason why the spiritual entity Tanisha takes on the role of a prophet to create an entirely new religion rather then simply reveal one or more prior religions is because none of them existed in a technologically advanced time and so lack the teachings necessary to instruct people how to live in an advanced society.
Transformatisya is heavily influenced by Christianity and Islam with convergent evolution on the Baha’i Faith, but without the non Abrahamic elements because they are considered redundant and unnecessary.

Idolatry remains the most severe sin, but the second most severe sin is anything that leads to or is a product of social isolation.

Tanisha also presents a lot of stories in the form of myths and allegories that are related to 21st century isolation.
