Sylvans are attuned the natural world--the outdoors, plants, animals, life energy, etc.

Examples:

• The fey
• Werefolk

Phenotypes

You must have at least one phenotype. You can have more than one, if they do not conflict. Phenotypes may have both advantages and disadvantages.

• Furry: You are a hybrid of human and animal, in a stable (non-shifting) form. Not compatible with Werefolk.
• Plantoid: You have green skin. You gain energy from sunlight, rather than from eating. You still need water, and occasional vitamins and minerals (about as often as a normal human would). You need at least 8 hours of sun exposure per day to feel "fed". Penalties include...whatever the fuck penalties exist for not eating enough, as if anyone even thought of that. TBI
• Werefolk: You have an animal form and a human form. Your animal form choice gives you certain abilities all the time, and (generally) more powerful abilities when shifted. You suffer an ability called Call of the Wild, which can compel you to transform and act in an animal manner in certain circumstances (e.g. predators are aroused to hunt by the scent of blood or fear). The full moon triggers your Call powerfully. Example subtypes: wolf, tiger, bear, etc.
• Underwater Native: You have a swim speed of 6, and you can breathe underwater. You can also breathe above water (because otherwise this ability would be terrible). However, you cannot stay out of the water indefinitely. You need at least 8 hours of "water time" per day. Outside of natural bodies of water, a bath or pool is ideal, but there are also conceivable magical or technological items to recirculate water over you, or even to provide a water-tight suit (sort of a reverse scuba gear) that keeps you hydrated 24/7.
• Fey: You have iron vulnerability, can be warded by effects that work on outsiders, and you can be bound by your words or by receiving gifts.
