Commune with nature

While meditating in an outdoor area, the Jedi bonds with all living creatures in the area and influences their development. Soil becomes more fertile, plants begin to grow, creatures sense tranquillity, etc. Anything but the simplest effects takes a great deal of time and effort to achieve. Sense is used to create the link with the Force and the new nature being developed while alter is used to create the new nature. Difficulty is a function of: how much matter is being shifted/created, proximity, the difference between the subject area and an open plain with neutral temperature and weather, and the amount of change sought. With an easy roll, the Jedi can create a feeling of tranquility. Higher rolls can grow grass, make flowers grow, attract animals, grow trees, make water spring from the land, and in theory terraforming would even be possible with this power. Deserts, areas with a Dark Side imprint, ocean banks, cold tundras, and vacuums may be the subject of this power, though as a rule, the more severe the existent climate is, the more difficult the roll.
