What happen there is that there are these triglavian NPCs that roam the system where a wormhole that leads to their home region Pochven has opened . These wormholes open to systems that were close to those that existed in highsec before triglavians took them and now they form Pochven region. They are strong in terms of AI, DPS, ewar .
