Historical records dating from pre-Gap times show that most planets in the Pact Worlds system once relied heavily upon magic to accomplish difficult tasks. The advancement of technology changed this, providing more economical solutions to complex problems. No longer was it necessary to spend years of dedicated study to learn how to produce magical light, when one could simply buy a cheap flashlight.
Magic was once divided into different traditions, the most common being divine and arcane magic. Such distinctions have largely been abandoned today (although a magic-user's power can still come from these different sources).
Magic & technology today
Magic and technology today coexist, and most technological items incorporate small amounts of magic in their functions or in their manufacturing.
