The game starts with a car accident taking place in the middle of nowhere, probably within the walking distance from London. It is heavily implied to have been caused by witches magic making the statues alive. Facts corraborate that story - the car ends up at the top of the tree, police inspector (as unskilled at puzzles as he may be) has no explanation how it could have been done.
However... (major game ending spoiler)
magic does not exist and is the result of slightly futuristic technology in place and hypnosis. That however is set up only for the region Labyrynthia was in, possibly an island
With that in mind, what is the true story behind the accident? Did I miss an explanation somewhere?
