Devil's board

You are participants in a city quest in the genre of a "mystical thriller." The legend promised an atmospheric adventure in the spirit of horror reality: an abandoned orphanage, mysterious disappearances, occult symbols. The organizers assured: everything is under control, everything is a game. But the deeper you go into the building, the more it seems that something has gone wrong. The "Northern Lights" orphanage was closed more than forty years ago — after an investigation into disappearances for which no one was ever found guilty. According to unconfirmed rumors, a secret cult operated in the basement, sacrificing inmates in the name of an unknown force. The only surviving girl, Ella, drew a board with letters and eyes for many years — until she was found dead in a psychiatric hospital ward. They say if you find this board, you can hear the voices of those who never left the orphanage walls. You wanted to solve the mystery. But now it is solving you.
