Crystal is a unique resource that is made from refining minerals found in deposits on most planets. It is highly valued as it powers most mechanics in buildings, ships, and defenses. This resource is used in most ships and research because it can power lasers and weapons systems.
This resource was first discovered when people began to look for a new power supply for their ships. Instead of using old electronic systems, they decided to use this new crystal to power them. This started the progress of space travel for most civilizations.
