| A Treasury of Creatures - Bygones and Umbrood of the Umbral Realms |
| The Umbra is a vast and deadly place, especially now that the Gauntlet cannot be crossed with ease. Many creatures live there, some of which are exceptionally dangerous, and others which can be very useful to an enterprising mage. The following creatures are playable in Mage: The Ascension Revised Edition, or can be adapted for any Umbral game. |
