As part of the shift cycle, the motions of the Isles sometimes brings them in contact with one another, either grazing coastlines or directly colliding. The resultant Collision event, similar to our earthquakes, can be either a mild rumble or extremely violent. Thanks to the advanced technology and mathematics of the Agori, Collision events can be predicted down to the second.
Collision events can be found in:
- The Prisoner (Shifting Isles Series, Book 1)
- Return to Tanas (Shifting Isles Series, Book 3)
- Broken (Shifting Isles Series, Book 4)
- Libertas (Shifting Isles Series, Book 9)
