[AlexanderHowl]

It should be noted that there is a difference between using magic to duplicate the effects of technology and using magic to augment existing technology. A society that used RPM (especially the Path of Nonexistence) to develop a TL(0+10)^ civilization would be an example of the former and could spread throughout the stars without much difficulty. A society that use standard magic to enchant TL4 ships to function in space would be an example of the latter and, quite honestly, would likely produce one-of-a-kind spacecraft because of the difficulty of the enchanting process.
