Artifactors. When you leave, close the doors

This city looks like St. Petersburg, but it's not that simple. Magical doors constantly open here - they lead to unknown places and destroy the streets, keeping the residents in fear. The doors are also a source of precious artifacts, which are hunted around the clock. The ruthless Clan intends to destroy the noble Guard and seize control of the city. Only a girl with a special gift can resist evil - but the gift does not obey her, her partner betrays her trust, and a villain known as Goodwin is obsessed with the idea of getting rid of her. How can you save both yourself and the magical city when everyone here has a secret, and the most terrifying of all is your own?
