Items in the environment that are integral to the story.
Stable Field EmitterEdit
Initially, the SFE wasn't functioning correctly, as it failed to stabilize Union. O'Neil mentions this during his first meeting with Sebastian. When it's found in City Hall later, Sebastian must power it up, then defend it from the effects of Obscura. After ninety seconds, the SFE will activate, preventing Union from further collapse.
Under Theodore's influence, O'Neil used the SFE to hide Theodore's Stronghold in Union. Sebastian and Torres end up having to destroy it to reveal the priest's domain and pursue him.
