While there are many marvelous but trifling Relics that would not help the average member of Aegis Kai Doru in the field, only a few truly useful in the battle against the supernatural are granted to agents. Agents who have gained possession of a Relic to use must have proven themselves extensively, and to have one is a symbol of great status among the Aegis Kai Doru's numbers. Likewise, no greater shame can befall an agent than to have a Relic broken, stolen, or lost on a mission; many who do so ritually kill themselves, especially if the Relic falls into the hands of the supernatural creature they were attempting to defeat with it.
Unlike many other Endowments, Relics can be used by anyone who knows the correct way to activate it; they are not limited to agents, hunters, or supernaturals.
- One-Eyed Kings: A set of two coins that can be used to spy on events in another nearby location.
- Skeleton Key: A key that cannot only unlock doors, but remove any trace of an intruder's passage.
- Eye of Hubris: A crystal that interferes with the use of magic in its vicinity.
- Orpheus' Eye: An apparently glass eye that allows the bearer to see into Twilight when held in the palm of the hand.
- Icarine Servitor: A wax doll that can be used as a servant or spy.
- Ringsel: Stones from the remains of a Buddhist master that allow the agent to heal themselves.
- Watchful Keris: A specially-made dagger that allows the bearer to gain the upper hand in an attack.
- Heart of Stone: When an electric current is passed through this stone, it causes great envy and eventually attracts monsters.
- Witch-Candle: A special candlestick with carvings that will attack anyone using magic nearby.
- Aegis Talisman: The agent who wears one gains special protection from physical and magical attacks.
- Dead Man's Face: A mask that can briefly allow a corpse to speak for a few minutes.
- Doru Talisman: A small spear amulet that can be used in the same way as full-sized weapon when needed.
- Blood of Pope Joan: A blessed item that also causes werewolves in its presence to weaken.
- Idol of Gévaudan: A small stone wolf idol, which causes werewolves to fight ferociously over it when splashed with werewolf blood.
- Phylactery of Commius: An ancient, small box that, when bound with a spirit, slows the aging of the bearer, causes the spirit to take damage for them, and helps the bearer speak with spirits.
- The Silver Key: A key that opens a door to the Hedge for approximately one minute, once per location.
- Heart of the Succubus: A round, bronze object about the size of a large man’s palm, and resembles a modern-day compass that detects demons in defiance of their Cover.
- Dream Relic: This isn’t a normal Relic; it’s an enhancement or modification to an existing Relic. This represents a Relic that’s been physically destroyed or otherwise lost forever, so now it only exists within the scope of dreams. The user is somehow bound to the destroyed Relic, so it appears with her whenever she manifests in a dream.
- Perseus' Mirrored Shield: The story goes, Athena gave this shield to Perseus so he could look into it and see Medusa’s reflection, protecting him from her petrifying gaze. He used this to behead the Beast. Now, the shield has a similar use; it protects the wielder from bestial Dread Powers.
- Saint George's Sword: This ancient broadsword was used by a soldier in Libya over one thousand years ago. The story says that fifteen thousand people converted to Christianity as recompense for the soldier’s work in slaying a great, poisonous dragon. Now, the sword has been kept as a legendary monster-slaying tool, specifically used against monsters and able to cause bleeding easily.
- Mask of Terror: Made from the face of a serial killer or a mask possessed by one, this relic inspires terror in those who look upon it similar to the terror the killer once inspired in a victim.
