The Waltz of the Ghosts

Three magicians stand before the colossal gates of the old castle, which have just opened out of nowhere. "Are we brave enough to go inside and see if it's really haunted?" asks Conrad, a little worried. "Yes, we can if we stick together!" reply Vicky and Mila in unison. But the gates are already creaking again... Will the three friends manage to explore the old ruins and find their way back outside before the haunted caste closes its gates again until the next full moon? Because one thing is certain: if the castle is indeed haunted by ghosts, they will certainly do everything in their power to stop our three curious magicians!
