Promethium Forge: Sector Magneticus Walls Half Kit

A fully magnetized and modular terrain set of walls. Make endless layouts; rooms, corridors, alleys, columns/pillars, or a mix of all of them.

This set is magnetized, and you can order this set with magnets for an additional charge, or provide your own magnets. You will need 150 magnets for the this walls-only set. Magnets are 6mm x 3mm round neodymium, and are widely available. For example, Canadian customers could buy magnets online in May 2025 for around $15CAD for 100 magnets.

Kit includes the complete cut of the Promethium Forge Sector Magneticus Walls Half Kit, made from 3mm MDF. This set is the same as the Sector Magneticus Walls Full Kit with exactly half the number of pieces, but with the full variety and only about half the price.

This half set includes 10 single wall units, 12 columns/pillars, and 9 double wall units.

Note that the terrain layout photo shows the full wall set, which is simply double the half kit. The main photo shows the actual types and the number of pieces of this assembled kit.

No need to buy the design or download it yourself. We provide the cut, unassembled sheets and you get the fun of building it.

Magnets included as an option (150 pieces). 

Does not include the figurines or baseplate terrain. Those are shown for reference only.
