The Lunarian facility specifically used to filter out impurities brought impurities to the moon. Now the Lunarians have to grovel to the goddess they pissed off centuries ago to help them stop the impurities, which would also stagnate Gensokyo as a result.
And the lore behind the pyramid is that it wasn’t belong to the Lunarian, it belong to an ancient Japanese kingdom with the Stage 5 boss as their princess (pic related)
Iwanaga-hime (Stage 6 boss), was their god, who refuse to come to Lunar Capital like other gods. Lunarian resort to brainwashing the princess and use her to convince the god to join Lunar Capital for centuries
Later on when the whole shenanigan with AI happened and threaten to destroy Lunar Capital, Toyohime seek out the god to help them damage control, in exchange she will get her princess back

Asama Yuiman was kidnapped and brainwashed by Lunarians for thousands of years, forced to do their bidding which included created living beings that have fake memories of being more than constructs. She was eventually completely mindbroken by information to the point of breaking down and failing to remember.

Since Reimu and Marisa freed her, she has the chance to recover, no longer under control of the Lunarians. However, she can never return to the life of innocence she once knew. Her old home is gone. And she's got plenty of mental trauma from the thousands of years of being brainwashed, not to mention her own guilt for having to create beings without purpose.

Yuiman is a broken girl that will need a lot of gentle love and care to help rehabilitate her. It could take many years, but would you be up to the task to bring her smile back?
