If you can Repeat the Power "this turn" (e.g., from "Powestorm" or "Gift of Strength"), then you may use another Power between the two uses of the repeated Power.
If the Power repeats itself (e.g., "Creepers Tear into Mortar" or "The Land Thrashes in Furious Pain") or you are granted the option to Repeat a Power "After" using it the first time (e.g., from "Relentless Punishment" or "Strength of the Waking Island"), then resolve the Power and anything else it triggers (e.g., "Vengeance of the Dead") before immediately Repeating it – you don't have a chance to use another Power first.

Similarly if you move a piece inland, you move it further away from the Ocean: each land it moves through must be further from (any) Ocean than the one it left.
All game notions of "closer" and "further" use Range – you never need a ruler, and a land that looks physically closer might not actually be at shorter Range! (Discussion elsewhere) Tags: Range, Move, Sweep into the Sea
For example, if you use Crops Wither and Fade, you always gain 2 fear and then you may choose whether you are replacing a City or a Town. On the other hand, on Tormenting Rotflies, you either choose everything above the "or" or everything below it.
If the Invaders are in a Coastal land, with Sweep into the Sea you can choose to either push them into the nearest Ocean (which is right there) or destroy them; with Ocean's Hungry Grasp in play, it will usually be better to push and Drown them.

The initial use of the Power targets a land and resolves (along with any non-Repeat actions it triggers).
This triggers both "Relentless Punishment" on that land and the Power's own Repeat instruction. Since the order is ambiguous, you choose which one happens first.
After the Power Repeats itself, "Relentless Punishment" triggers again on the second land targeted.
Because "Relentless Punishment" counts allprior uses of the Power, using that special rule a second time can get quite expensive (Power's Energy Cost + 1 Energy for the first use + 1 Energy per initial "Relentless Punishment" use + 1 Energy for the self-Repeat use)!
