When Celia had discovered the dictionary of the runes and the material for making permanent engravings, she immediately thought that this was exactly what she needed.
There were several things that bothered her, and those runes might be the solution to her problems. Her biggest problem was giving free access to the dimension to the boys and now to the magic beasts. Then these shapeshifter necklaces didn't suit her at all because she couldn't choose what she was going to look like, at least her face because the rest of her body remained completely the same, so she wanted to find a way to improve their disguises.
And then there was the problem of the communication stones, they didn't work when they were in the dimension.
After scrupulously studying all the runes and after reading all the notes that the cave mage had left all over these books, Celia was sure that she could sort out all her little problems with them.
