The only W-Space system with NPC stations — a hub, not a farming ground
Thera is a single, unique shattered wormhole system — not a class with hundreds of systems like C1–C6. Introduced in the Rhea expansion (December 2014), it's the only wormhole-space system with NPC stations.
It's the busiest crossroads in New Eden: a dozen or so wormholes connect it to high-, low-, and null-sec at any given time, on top of its own wormhole-space statics. That makes it a waypoint for explorers, roamers, and smugglers rather than a system you farm like C1–C6.
