Finally, after an hour of wandering here and there in the palace, Celia saw a silver halo around a wall, there was a large painting on it.
It represented a big battle and looked a lot like Anaya's drawing, but the characters were differents of course.
She approached the painting and tried to grope on the wall for a mechanism that could open a secret door. Groping around, she found a relief on the painting, looking closer and rubbing a bit to remove the paint she made an amazing discovery, it was another pentagram.
The relief she had felt was a pentagram carved into the wall, Celia tried to press on it or slide it up and down or right to left but nothing worked.
