Exclusion Zone

All Trade Centers have "Exclusion Zones." They are, in essence, neutral/safe territory. Monsters will not enter Exclusion Zones of their own accord, and neither dangerous monsters nor plants will spawn inside one. Sapient Beings who attack other Sapient Beings inside Exclusion Zones are subject to some sort of System-enforced sanction, the nature of which is unknown as of the end of Mind Games.
