A response I made about the lore in the rulebook on Boardgame Geek made me start thinking about gathering the different names found within the book and spirit panels and putting them online. Not exactly as a reference document, but just so they are out here for easy perusing.
Let us start with the current playable spirits “everyone” is familiar with
Lightning’s Swift Strike
Vital Strength of the Earth
Shadows Flicker Like Flame
River Surges in Sunlight
A Spread of Rampant Green
Thunderspeaker (Formerly Bright Thunder Roars)
Heart of the Wildfire
Ocean’s Hungry Grasp
Bringer of Dreams and Nightmares
Serpent Slumbering Beneath the Island
Keeper of the Forbidden Wilds
Sharp Fangs Behind the Leaves
Now, here are some Spirits mentioned, but who we do not see directly
Stalker of Hidden Secrets (imprisoned Bright Thunder Roars, leading to Thunderspeaker)
Volcano Looming High (Probably also “The Volcano” mentioned as one of the parents of Heart of the Wildfire and as a creator of the Island, similar to the Serpent)
The Green (Possibly Spread of Rampant Green, partially gave birth to Heart of the Wildfire)
The Pathmaker (has a Realm, was also mentioned in regards to the spirits of Dead Dahan if memory serves)
Voice of the Deepest Gorge (no longer around?)
Watcher Acts Not
And implied but not named there is the Storm Spirit which birthed Lightning’s Swift Strike
Next some events, named or not
The Years of the Relentless Sun which Shadows Flicker Like Flame helped “combat”
The Ice Curse which feeds River Surges in Sunlight
First Reckoning
Second Reckoning (This is implied to be super important, but no details are given)
Other Names of Potential Interest
Servant Cults (these seem like they could be important, perhaps related to the Second Reckoning)
