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.
The target produces income as if it were a Mine of its Level instead of a Forest; you choose which type of Mine (Lightstone or Darkstone) it acts as when you register the performance of this ritual. The target also produces 2 additional Silvermarks or Ironmarks, whichever is not normally produced by the type of Mine it is acting as for the duration of the effect.
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).
