Drifting in his magical ship above Ifreann, Cabot would, during breaks from his arcane research, sketch what he saw through his telescope.
Unfortunately Cabots' magical ship was attacked before before he could complete this map. As he searches to find a way to rebuild his ship, he notes when a map of a particular region is encountered.
Ifreann is the 7th planet circling the blue-white giant star Bellatrix. Due to the the high energy level of this star, life did not evolve naturally on Ifreann but rather, came by other means. The natural energy of its' star accounts for the greater availability of magic. Earth's star, Sol, just doesn't provide as much power as does Bellatrix.
Unfortunately, Ifreann is 'doomed' to never develop technology! The ultraviolet and x-ray output of Bellatrix is so great that any widespread technology much beyond the present would result in a loss of ozone, and resultant destruction of life on the planet.
A few of the most knowledgeable wizards and some of the ancient dragons know this, but it isn't common knowledge. It would be an understatement to say that this is one of the reasons dragons and wizards don't like technology!
