An Elf is a product of his environment, and is a part of it as well. Calling on his bond with other living things, an Elf may shape them to his desires through music which they also call Faeterna's Gift.

Similar to Form magic except much less powerful, Lifesong may be enhanced through the use of Form, though elves generally abhor magic. With Lifesong, an elf may coax a plant to grow in a certain shape or direction, even making a home out of a tree if he takes enough time.

A plant shaped by Lifesong does not grow any faster unless the Elf enhances his song with magic or sings with many other elves; it does, however, grow about as fast as it would during the spring, or as a seedling. The Elf can make the plant denser, even as hard as steel in the case of the harder woods, and so much of elven community doesn't even use metal unless the tool or weapon is expected to come into contact with, for instance, fire. An elf can make sheer clothing from petals, weapons as hard as steel, or just shape his or her garden. Such a plant which is harvested will die as usual though it will retain its shape, but some elves are able to coax a plant's roots to change so that it can continue growing. Experts with this skill are known to have entire wardrobes which are still alive, fed through sunlight and tiny hair-like roots which catch water and nutrients from the air.

First level enables the shaping of plants; second level enables changing the density and properties of the plant. Third level ennables the healing of non-plant life (as per the use of Form) and enhance natural abilities the life-form already has (making a viper's poison deadlier, for instance.) Expert allows the alteration of life-forms to breed true, with the exception of shape--a flower altered into a shirt will have offspring that look like the original flower, though if the parent was made sheer, or dense, or tough, or elastic, such properties would remain.

Lifesong does not work on living things which are sentient or magical in nature without that being's consent (which can be falsely obtained) because Faeterna's Gift does not allow it.
