A system of premade walls that act as a early game form of defense.

Features of these segments:
Complete interlocking of the stone blocks allow sections to fall without taking the whole row down.
Redundant Wooden supports.
Compact size, allows the player to build walls in tight spots.

This includes:
Straight Wall Segment
Straight Door Wall Segment
Straight Banner Wall Segment
Corner Wall Segment
Inner Corner Wall Segment
Corner Tower Wall Segment
U Bend Wall Segment
End Wall segments Left/Right

(There are no stairs to the walls, but seeing as its four blocks to place I left the choice to place the stairs anywhere to the player)

I'll be adding to this as I continue to find interesting uses for these walls.
