Grading of Radio-Arcana Phenomena Beyond Evolver Territory
-1: Null magic. Magical effects actively suppressed. Active discomfort for magical beings. (All bar Humans. Domus-born Fae somewhat less affected.) Largely theoretical at this point, few locations, none confirmed.
0: Baseline New Earth. Magic functions as experienced within London (barring anomaly zones). This is what you’re used to.
1: Magical Confluence. Magical effects more potent but also controlled. Standard level at summits, leyline nexi, places of power, confluences. Magic safe and predictable.
2: Wild Magic: Magical effects heightened, unpredictable. Expected patterns of rituals, leyline adjustments, etc no longer reliable. Dangerous without proper training & preparation, largely safe with.
3: Entropic Magic: Supernatural effects constant, unpreventable. Mutation likely, other inexplicable events common. Actively dangerous. Appropriate countermeasures unreliable, vary from lv 3 site to lv 3 site.
4: Primordial Magic: Magic raw, active, uncontrollable. Behaves as storm, earthquake, other natural disaster. Cognitohazards widespread, Monsters here may be unable to survive outside lv 4 zones. Extremely dangerous.
5: Event Horizons: London’s anomalies, wasteland bomb sites. If you go here, you do not return. Do not enter lv 5 areas.
