Text of the card does not specify any duration of its effect. I think that it is a mistake.
I propose the following erratum:
"Ritual. Tap a sage to change until end of turn one Wilderness to a Border-land or Shadow-land or one Shadow-land to a Wilderness or one Border-land to a Wilderness . Sage makes a corruption check. '...No one has ever caught old Tom walking in the forest, wading in the water, leaping on the hill-tops under light and shadow. He has no fear.' -LotRI"
