Aedificarium is the ability to craft, weave, shape, or otherwise manipulate the fabric of reality derived from the energy of the Foundation. In order to access the power of the Foundation, one musgt have a tool or object made of a pure substance: non-hybridized wood, pure elemental material (iron, silver, gold, etc.), unblended stones, threads, powders. The purer something is, the stronger the Foundational energy in it is. One can invoke Foundation from water, but liquid oxygen would be stronger.

The power of the Foundation can sometimes manifest inadvertently when using pure materials. A home built from pure woods and stones would find that works created within it are imporved. Even the spiderwebs in the home would resonate with the power. Indeed, on occasion, the power of the Foundation might spontaneously manifest created objects in subtle ways (cobwebs might form without a spider's presence, for instance), though this is rarer.

There are two kinds of aedificarium: innate and learned.

Innate:
Shemir shaping powers
