Since Continuum is something that involves space and time, it's appropriate to have an effect that involves both Aether and Time.
I'm thinking about an effect that makes modifications in time when space is modified and vice versa.
Time modifications are pretty obvious (Reverse Time|Rewind, Delay), but space modifications are not so obvious.
The only space modifications i can think are Phase Shield and (somewhat stretched) Immortal creatures.
If we can define space modifications in Elements, then we can relate them with time modifications.
