An Arkanum is a mysterious divine(?) being, associated with an element of the physical or spiritual world, that is able to control the deadly wilds of The Nexus. The most powerful Arkana shape the inhabitable lands themselves, while smaller ones with more specific domains exert their power on the scale of individual people and objects.
The Arkana with major territories on the Nexus are:
- Gobannus, Arkanum of the Forge (Cinnabar Keep)
- Marzanna, Arkanum of the Frost (Everfrost)
- Antikythera, Arkanum of the Gate (Jetstream Hollow)
- Telesphoros, Arkanum of the Grimoire (Delos)
- Hvergelmir, Arkanum of the Oak (Woods of Silence)
- Zephyr, Arkanum of the Sky (Whirlwind Sanctuary)
- Nimue, Arkanum of the Sword (August Sands)
- Seraph, Arkanum of the Tower (Mot-Seraph)
- Odyssey, Arkanum of the Wheel (The Trains)
