Time was moving faster, slower, or even backwards, but only physical processes other than movement were affected here, except when time went backwards. The other deteriorating effect of the spell was the relative time on the island. Also, the number of demons that would appear over time on Earth was supposed to increase due to the radiation, but this never happened because they undid the spell before too much happened. If you happened to be anchored in one of the times that you briefly appeared in, when you are unanchored, you will go straight back to Hybras. The area from which you could be taken from at Hybras, and the amount of silver you needed to anchor you was increasing. The first, more simple effect was that if someone was too close to the original spell, you would be thrown across times, never in one time for too long. This meant that the additional radiation from Earth began unraveling the spell, causing two strange effects, and each was getting worse in its own way. Early in the book, it is revealed that ten thousand years ago, the demons decided to lift their island out of time, but were sabotaged. In Artemis Fowl and the Lost Colony, time travel is not explained very thoroughly, but time seems to have a mind of its own.

It is also stated that fairies may choose to enter the time-stop at any time inside of it, but this is never used. This has the added effects that people can be sent into or out of the time-stop thru a gate, anything in the time-stop does not effect anything outside, anyone inside the time-stop cannot fall asleep without sedatives, and anyone that is asleep leaves the time-stop. This causes the time of day inside the bubble to stand still, while everyone inside moves in sync with the world outside. In Artemis Fowl, a 'time-stop' is placed over Fowl manor. Manipulation of time is a main theme of The Lost Colony and The Time Paradox, appears in The Last Guardian and Artemis Fowl

Fairies may manipulate time through various means, like Elvin warlocks stopping time or Demon warlocks moving things thru the time streams, and this manipulation has various ramifications across the series.
