Companion Souls are created in the mind of the creator, with iron and pieces of soul. One of these pieces comes from the forger, bonding Soul and Master. The various pieces of soul combine to create one new, whole soul. This new soul allows for the Soul to take on any appearance when Unsealed. However, Souls cannot remain in Unsealed form for long, due to the fact to remain Unsealed the Souls taps into the Master's energy. Companion Souls can be forged only once every 100 Dimensional Years, due to the strain of creating them. However, you must have someone teach you how to forge a Companion Soul the first time, or you will be unable to do so ever. You must continue to forge them every year as well, or you will never be able to do so again. Each soul takes one week to forge.
