Transformice's Deity is the grand spirit of Transformice. She created the mice, giving them life and the unusual power to transform into inanimate objects. As the years went by, the Deity then used her mystical power to create a Shaman, a spiritual guide who helps the mice gather cheese when the block is just too hard to reach. The number of Shamans increased as the number of mice increased, and the Deity now looks for on everyone with a smile on her face. Legend tells that if you wait in Room 801 long enough, in the year 2020, the Deity will come down from the heavens and reward the best and kindest mice with the ultimate gift- Something that no other mouse would ever receive in any update.
The legend is fake, I just made that up. If Atelier801 wants to make that legend a reality, it's their option <3
