The process is quite similar to that of the Eternal Fierce Sun, continuing to provide devout faith to Shire.
But it isn't about "admiring the Goddess Shire"; it's about fearing the day when the Dark Night Goddess might truly awaken from the river of time. Seeing that the higher-ups still arranged for people to believe in Her, She might show a bit of leniency.
After all, Goddess Shire doesn't have the energy to eliminate every believer, but eliminating the higher-ups and their descendants is still very easy.
To avoid being implicated, they specifically left Shire's most loyal devotees here, creating for them an ecological park.
And then...
Those higher-ups, with a thousand sins, sealed everyone in this large relic and exiled the entire area to the shadow plane.
They feared these so-called "fanatics" later regretted it and stopped believing in the Dark Night Goddess.
