Great Aurora

The Great Aurora was an event that changed the plane of Lorwyn to its dark and twisted counterpart Shadowmoor, and vice versa. Each Great Aurora was caused by Oona through her lengthening of the normal days and nights of Lorwyn to last for centuries at a time. The Great Aurora depicted in the Lorwyn and Shadowmoor block novels occurred sooner than Oona intended it to, as a result of the Great Mending. As a precaution, Oona killed the elf Maralen in order to make a duplicate of the elf to house her memories in. Oona did this because she was afraid the early Aurora would affect her like the rest of the plane because she did not cause it.

This event was ended by Oona's defeat at the hands of Maralen and her companions.
