"NEEDS BASEPLATES" - pesgores
Baseplates are plates that are thinner than normal that can serve as bases for Brikreations or other stuff.
Pesgores insists that all creations need baseplates to be cool, especially battlefields, but no one really cares.
Baseplates come in several varieties of sizes: 32 x 48, 32 x 32, and 48 x 48 are just some of them. Some 32 x 32 and 32 x 48 baseplates have patterns like roads, rivers, and some have raised sections. These last kind are called raised baseplates.
Outside of what most consider to be their dimension exists another where minifigs live on "Plate Worlds", instead of planets. These plate worlds are flat and finite. beginning and ending only where the baseplates stop
