The surface of Bodue is almost entirely covered in enormous Mother Lomoi (Boduan) roots. In a full grown tree, they slope for about three miles before the trunk becomes almost fully vertical. The interlocking slopes of various trees create a topology that resembles a network of river valleys. As the divisions between root systems are distinctly visible (and occasionally become rivers), they are often used as boundaries between clans.
Boduan roots grow with the tree until they meet another's root system. The effect is usually a zigzag pattern of the two interlocking systems which remain separate.
Rootlands tend to lack a Pseudofloor in higher elevations, due to erosion.
