This  beechwood disc, about the diameter of a large apple, is carved with a φ symbol on the reverse face, and an auroch rampant on the obverse. The classicum and its paired disc, a discus geminus, are Fixed Arcane Connections to each other. Its Discus Geminus has a matching φ symbol on the reverse face, and a tower on the obverse, and is held by Arx Caeles for use with its Patiens Artifcicium.

When the classicum is activated by tapping the auroch face three times quickly with a fingertip, the paired discus geminus emits a clear tone and turns bright orange for a few seconds.

This large four-wheeled wagon, or carrum, is about four feet wide and twelve feet long at the bed, with high sloping sides and a driver seat just behind the partial front wall. The center panel of the right side is hinged to serve as an access ramp. Four shallow arches support a stretched canvas cover, with an awning over the front. From bed to the top of the arches, the wagon is about eight feet high, with another two feet from the bottom of the wheels to the bed, for a total ground height of just over ten feet. Each carrum has a functional limber and may be harnessed to a team for mundane movement. Suitable horse collars and harnesses are typically stored beneath the driver's seat when not in use.

A carrum is enchanted to move through the air at speeds as fast as a flying bird, or along the ground on its wheels at a reduced pace, at the direction of the driver. The driver must be on the carrum and possess a special ring keyed to the enchantment to issue commands, and must concentrate to change direction or speed, although the carrum will maintain its altitude, speed, and direction of travel without concentration by the user. Control by the user is based upon the result of a Finesse roll, with higher speeds or more difficult maneuvers necessitating higher Finesse results.

The front panel, facing the driver's seat, is carved with an image of an auroch head and inlaid in bright yellow enamel. The brass/silver alloy rings keyed to this enchantment bear an auroch head in bas relief, with matching yellow enamel.

This carrum luteum was enchanted by Aurelius Aestivus Bonisagi and Astrea Jerbitonis in 1275 AD.

A miniature hearth carved from black basalt stone, on the end of an iron rod with a hornbeam handle, which can create a large magical fire, hot enough for any baking or cooking use. The enchantment is activated and controlled by touching the stone to a hearth and speaking the command word "incoendo." The heat of the flames may be adjusted by the command words "candens" (hotter) and "alsus" (cooler), and the amount of flame produced may be varied by the command words "magis" (greater) and "minus" (lesser); any fire created by a given Lapis Foci may be cancelled by touching the stone to the hearth and speaking the command word "coryza," fire created by a Lapis Foci will cease at each Sun event regardless.

The Lapis Foci miniature hearth is inscribed "Focus" along the handle.
