Cannons are hand forged by master craftsmen, and every cannon is different with little standardisation in the way of calibres or length. Individual cannon can be extremely large, but most are either large cannons, such as the Empire's Great Cannon, or smaller cannons. Details are given below for typical examples. The difference between the two sorts is range and damage. Bigger cannons carry a larger charge and so have a longer range and cause more damage.

Cannons are cast from iron or bronze and are built into solid carriages. They are very difficult to destroy although the enemy may try to attack them with other engines of war, large monsters or magic for example. They therefore have a profile like a creature with a Toughness value and a number of wounds which they can sustain before they are destroyed. As with other details these might vary in specific cases, but a typical cannon has a value as shown here. The move rate is the speed the cannon can be moved by a full human crew assuming it has wheels. A cannon which does not have wheels cannot be moved. If any crew are slain the cannon's speed is reduced proportionally.

A cannon cannot move and shoot in the same turn except to turn to face its target. Generally speaking cannons have such a long range that it is pointless moving them about.
