The Satanic Temple is preparing to hold the "largest gathering in history" in a chilling event
The gathering is a convention for those who practise Satanism and the initial plan was rejected by the Mayor of Boston, Massachusetts, in the US.
The Salem-based religious organisation is hoping to mark SatanCon 2023 as an event in downtown Boston this April, even after Mayor Michelle Wu rejected the group's plans.
With the Satanic Temple committed to safety, the organisation have made it clear that "masks" must be worn, although they will not allow "gaiters, bandanas, and cloth masks".
The event will mark the Satanic Temple's 10-year established anniversary and followers of the edgy religion will take part in the "Hexennacht in Boston".
Translated from German to English, that marks the celebration as "Witches Night", the ancient pagan holiday that will this year feature a "Satanic marketplace".
After many discussions about the event with Mayor Wu, the Satanic Temple has decided to dedicate the celebration to her and "her unconstitutional efforts to keep TST out of Boston's public spaces."
However, this is not the first time the Satanic Temple has had a run in with the City Hall office, as numerous other troubles have seen a feud develop.
Just last year the temple found themselves at odds with the city yet again, after former Mayor Jim Lane denied a request to invoke Satan at a City Council meeting.
The Satanic Temple also caused outrage in November after a new after school club founded by the organisation and the Reason Alliance was introduced at Golden Hills Elementary School in Tehachapi, California.
Parents slammed the primary school after the 'disgusting' After School Satan Club was set up for children as young as five.
One parent described the club as 'disgusting' while another said it was a 'mistake' to allow the extracurricular group.
However creator of the club Paul Hicks hit back at the parents and said the reaction was to be expected.
Mr Hicks, who is also a critical thinking professor, said: "We've already gotten threats against us. As I would often say, there's no hate like Christian love."
A spokesperson for the After School Satan Club said at the time that the club is supposed to 'educate children and encourage critical thinking', according to Lucien Greaves.
She added that despite the controversial name, the group does not teach Satanism to kids.
