Proposed Canon

While magic and natural magical abilities are used in many activities and tasks on Erf, from digging holes to long-range communications, some machines are used based on basic mechanical principles such knowledge of the six classical simple machines (lever, wheel and axle, pulley, inclined plane, wedge, and screw).

Machines of Erfworld

Siege Tower

The siege towers demonstrate the use of the wheel and axle and of the inclined plane.


Rudimentary trebuchets are seen on the roofs of the new city of Gobwin_Knob. TBFGK Epilogue 3 These trebuchets were popped along with the rest of city on the turn following the Battle for GK. Trebuchets use the lever and the wheel and axle.


Galleons, like all sailing ships, are quite complex pieces of carpentry. A ship's rigging uses pulleys and the hull itself is a wedge.

Defensive Engines

Faq is described as having "Defensive engines in various states of assembly...".LIAB Prologue 16 The names and nature of these machines is unknown, as is who assembles them and how.

Miscellaneous Technology

Waste Management

Some Transylvitian cities have water closets that conduct water through lead pipes. TBFGK Epilogue 19 Other sides, such as Gobwin Knob, lack the full implementation of this technology and must sometimes resort to chamber pots.


  • Units like galleons and siege towers pop, much like the trebuchets popped when GK was upgraded.
  • There is a specialized infantry unit that has the knowledge necessary to build these machines. Any unit which has the special ability of Fabrication, like Twolls is a plausible candidate.
  • Machines can pop assembled, as in the case of the new GK, which had shmuckers to spare at the time, or unassembled, as in the new Faq, which had to limit its spending.
  • Machines require a separate crew to operate; the siege towers, for example, are shown being pushed into place by Battle Bears. All siege equipment may operate similarly.

The Roman-Italian influenced Transylvitians used lead pipes in their plumbing, much as the Romans did.
