The Basiphem inhabit the emergent-layer of the Llanowar forest; they live in the crowns of the oldest and tallest stoneroot trees. They are a hardy breed with muscular phsyiques and are indifferent to inclement weather. The Basiphem act as the protectors and guardians of the forest. Each clan is an independent unit, led by some wise elders. Some of the honored elders, known as the Woodborne, have never set foot on the ground, even during the Phyrexian invasion.
The Basiphem took terrible losses during the invasion. Their ultimate failure to protect the forest still burdens the entire elfhame.
