Echoes of Salvation Prayer Book

In a world where God has been forgotten, angels and demons wage a spiritual war across the mortal realm, leaving devastation in their wake. A chosen few keep hope alive as the last lights in a world consumed by darkness. This core prayer book provides the prayers and spells used during play and supports the ERP—Experienced Role-Playing—system. The accompanying rule book is required for full use.
