Страшная тайна подземелья

If the adults strictly forbade going to the basement, where the girl Masha disappeared without a trace long ago, then, of course, there will be a curious trio of schoolchildren who opened the door that should never have been opened. And now they are in the Twilight world, where the Gloomy Shadow dwells. Amazing worlds Beyond the Darkness, ghostly wolves, swamp dragons, puzzles and secrets at every turn. Only here will the kids understand that we should judge others not by appearance and words, but by deeds.
How will this fun and incredible adventure end? It’s terr-rr-ibly interesting! Let’s hurry to open... no, just not the door to the black basement!
