Whats this I hear about Protoss buildings needing energy?
A. Protoss technology draws its energy from a psionic web generated by nodes arrayed around the Protoss homeworld of Aiur. An off-world Protoss colony must be able to tap into this energy matrix to power its buildings. The central building of a Protoss colony is called a Nexus. The Nexus maintains a link to Aiur and can provide power to any buildings in close proximity. Floating Pylons are used to channel this psionic energy and extend the range of the energy web. By building a network of Pylons, the Protoss can expand their base as they grow. All other structures can only be gated in within the influence range of a Pylon or Nexus. If something happens to their power (e.g., the Pylons are destroyed) they shut down until they can be reconnected to the web. A Protoss player must be organized about building extra Pylons, reinforc- ing defenses with Shield Batteries, and maximizing land usage.
