Freiyon Fables: The Rochester Runes

Three children move into a mansion once owned by their grandparents, and on moving day they uncover a terrible curse which can only be broken by collecting seven magical rune stones in a new world. Charles, Robert and Sarah Rochester have only just moved into their grandparents old manor, a place they know nearly nothing about. But soon after moving in, it becomes obvious that there's hidden secrets in the family history, and a terrible 'curse' that has plagued the family before is now awoken again. Now to save themselves and their family, the three children must find the location of the mysterious Rochester Runes, seven rune stones that supposedly grant wishes once all have been collected. The only issue is that Charles has uncovered a secret passage in the Mansion that leads to a portal to a different world. A world full of talking animals, sentient trees, and lots of magic. And before they realize it, the children find themselves not only exploring this new world and learning about the fun and dangers within it, but also find themselves in the middle of a battle between creations from their world, and inhabitants from the new world. And they are the only ones that can save both worlds before it is too late.
