Sinnoh is a cold northern region split in half by the massive Mt. Coronet. In the east you'll find windy canyons and spooky forests, while the west is home to many a bustling city and the Great Marsh. Venture north and you'll come across a quiet land covered in a thick blanket of snow.
Legend has it that the very highest peak of Coronet was where the legendary Pok?mon of time and space were created by Arceus.
