According to Wikipedia, a voxel (or volumetric pixel) “represents a value on a regular grid in three-dimensional space”. In the context of RPG in a Box, voxels are the building blocks (think 1×1 LEGO bricks) used in the creation of your game's tiles, objects, and characters. Each voxel is visually represented in the Voxel Editor as a cube and possesses a unique XYZ coordinate within the editor's three-dimensional grid.
