Temporal Travel Technology existed for many centuries, and is still considered to be experimental by the magic industry. Several government agencies are currently looking into its potential long-term effects.
Magic companies are using temporal travel to deliver products before they are ordered, and there is also a time travel spell called GOLMAC. Also, the ancient Hourglass of Phee allows travel backwards and forwards in time, although only in Phee itself.
It is also known that another hourglass of time travel is mystically connected to one of the Cubes of Foundation. This hourglass allows travel to the early days of an age-old castle in the Eastlands. Another time travel spell is GIRGOL, which stops time but allows the caster to move about as normal for a brief amount of "time."
