Zgredism
Zgredism/Zgredoism (as of 2021) is the largest religion practiced in Polish nations, just before Onionism.
Beliefs
Zgredism is a cult of frogs. These selected frogs are often called zgredos.
Frogs are considered holy creatures and they are posted in unrelated places to mark it as visited by a zgredoist - signs, Discord servers, emojis, photos - strenghtening the relationship with an abstract community it created.
History
Bajzyl - creator of Zgredomadzenie [from: zgromadzenie - assembly; lit. zgredossembly] - which is a founding group, found a photo of a frowned-looking black rain frog. People have decided to worship it and soon it became the most practiced religious group in Poland.
Phrase zgredo most probably originates from Inspektor_Gadzyt, who calls himself Zgredo on Discord and has a frog profile picture. He was an important Polish politician, diplomat, and is a mayor of Slavowice. He is not associated with anything zgredoistic but acknowledges their existence. His messages are sometimes taken out of context for religious practices.
Zgredocrusades
A list of Polish and other towns for the whole month of July 2021 was made, where each day a zgredo is placed near or inside it, called Zgredokrucjaty (Zgredocrusades). Articles with pictures were being released on 3meraldK's polish EMC community discord until 17.07.2021, when he went mad with posting frog gore and locked the channel. It then was moved to the original Polish Discord, where it is currently. The channel is multi-purpose, as articles about other server-related events are made, and it's open to outside contributions.
Archives of past articles are available here as a pastebin (in polish only).
Statues
In early March 2021, on a private zgredoist server, first proper zgredo figurines were designed by Kieubasiarz, soon after rebuilt in Zloty Stok, where the world's first two (normal and mini) still stand.
Zgredo
Sometimes called zgredo-pomnik (zgredo-statue) or big zgredo. As of now, two officially exist: in Zloty Stok and Wrocław (by Bajzyl, built on the occasion of crusades).
Mini-zgredo
Designed at the same time as big zgredo, but built on this server back in March. It's the most commonly used statue for crusades or space-limited towns. Usually dark oak, but on special occasions anything else that has stair and slab versions.
Micro-zgredo
Made by accident by UndoneArtist in Rzeszów somewhen before July. It was supposed to be a mini-zgredo made from memory, turned out to be smaller, but it's been accepted as canon too. It's lacking slabs on top and can be a block shorter. Sometimes used by him on crusades.
