Among the forests, jungles, and sunlit valleys of not only the Material Plane but also the Feywild, green giants wander and rest alone or in small groups. Green giants are remarkably rare, friendly, and gentle giants. They rank between hill giants and stone giants in the Ordning of Giants, but they are so uncommon that they are often forgotten. The boulders they throw are often chunks of wood or amber, rather than pure rock.

Verdant Green. Green giants are green because their connection to the natural world manifests in a plant-like nature. Their green skin, which is as thick and tough as a tropical plant's hardy skin, is covered with small vines, leaves, moss, thorns, and other bits of flora. Their dark green hair can seem nearly black without good lighting, but it is usually threaded with leaves, flowers, and twigs. These giants begin their lives as giant seeds which must be planted in the ground and tended to for many years before finally emerging as green giant children.

Green giants prefer to live in areas that are as verdant as they themselves are. The forests and grasslands they inhabit are relatively abundant, and when their homes no longer suit them, they take a fallen tree as a walking staff and set out on a wandering journey to find a new forest. Despite their wide ranging habitats, these giants are so rare that many regard them as a myth. Most green giants are content to live their long lives without increasing their numbers or building families.

Sunbathing Pacifists. Green giants live lethargic and restful lives. They love basking in sunlight or soaking in clean water (preferably both at the same time). Rather than concern themselves with war, politics, gluttony, or knowledge, these giants exist peacefully and patiently, content to live in serene locations and appreciate the beauty inherent in nature. Green giants abhor violence, and they are so careful with their strength that they can pluck a tiny baby bird from the ground and return it to its nest without misplacing a single feather. When they must defend themselves or their lands from aggressors, green giants seek the aid of their friends and allies.

Patient Cultivators. Green giants enjoy tending to plants and animals in their verdant homes, such as deer, flowers, or songbirds. They treat their plants like beloved pets, and treat their animal friends like children.

Green giants are congenial and friendly, approaching relationships with other sentient beings with just as much patience and concern as they do with flora and fauna. Once a green giant has decided to befriend someone, they make regular visits every few months to speak with them, listening attentively and trying to aid them with the problems in their lives. They commonly make friends with farmers and hunters, but anyone that journeys through a secluded forest or jungle might catch the attention of a green giant and start a friendship that lasts long after they leave the area. Green giants watch their humanoid friends grow, learn, thrive, and flourish over the course of a humanoid lifetime, taking joy in the accomplishments of their friends.

Photosynthesis. As a magical plant, green giants can feed themselves for the day without eating anything by staying in sunlight and clean water for at least 1 hour.
