This Numen allows a spirit to change its form from ephemera to matter, dropping it abruptly through the Gauntlet into the material world. The spirit’s physical form appears in the material world just as it did in the Shadow, and all its Numina and Influences function as normal. All rules for spirit traits in the spirit world apply equally to a Materialized spirit. Spend three points of Essence and roll the spirit’s Power + Finesse to allow the spirit to reshape itself into matter. The number of successes indicates the number of hours that the spirit can remain in the material world before reverting to ephemera. The spirit must then choose between remaining in the material world (and either anchoring itself or losing a point of Essence every hour) or slipping immediately back through the Gauntlet.
