You target one Enterprise with this ritual, the owner of which must be present for the entire performance of the ritual.
This ritual can only target a Forest or Mine.
The target produces Trading Marks as usual, but instead of its other income it produces Aether Crystals as if it were an Aether Vent of its level.
The effects of this ritual last until the end of the next Round of Downtime or another Enterprise Sorcery is placed on the target (whichever comes first).
