Verdorite

Source Book of the Dead pg. 164
When disaster befalls the natural world, a different kind of undead may rise, entirely unlike risen humanoids. Most plants, fish, insects, and other animals don't possess a psychology complex enough to experience the emotional catharsis required to return as undead without intervention from an outside force.

Mass extinction can serve as that outside force. Humanoids clear-cutting an entire forest or a seaside community wiping out a species critical to their ecosystem can spawn a verdorite. The collective spiritual energy and emotional distress of a dying biome powers these undead, formed as conglomerates or representatives.

About Verdorites

Verdorites are the enraged spectral echoes left behind when an ecosystem experiences a catastrophic collapse. Calling upon the essences of millions of extinguished plants and animals, they punish any they deem responsible for the disaster, as well as whoever might try to harm the lands to which they are bound.

Once-Mortal Waldgeists

Sometimes druids, fey, gnomes, and other powerful primal spellcasters with a deep connection to a specific woodland ritually sacrifice their lives to the forest, intentionally dying so they can rise as a waldgeist and protect their home for all time.
