Sprigg
Sprigg is a Wunderran human who seems to be involved into extra planar stuff, and with technology and objects that doesn't seem to be within our grasp, at least yet.
Update from 28 - An Even Newer Frontier:
↪ Sprigg saved us and agreed to take us under his wing, being our responsible and superior.
Update from 37 - Against the Odds:
↪ Sprigg explained and demonstrated his power (see Godhood section), which led us to Nowhere, and confirmed he is a child of a Wonder (the Planes to be precise).
Race: Human (and Demi-God known as a Wonders)
Identity: He/Him
Role: S Rank Member of the Operation SideSpear
First met: 22 - Dome & Devil
From what we've seen, he seems an upbeat person and quickly considered us to be friendly. Even if he looks like a young human adult, I suspect he is older than that.
Status: Friendly
Sprigg mentioned he has a cool dad when he had to explain his demi-god origin, and as he's from Wundera, just the fact I asked if he's the child of a Wonder, he immediately deflected it, meaning it's a sensible chord. I don't know what's the relation with his Wonder Dad, but it's something to ask and let time pass between each question.
The question is, from which wonder is he the child?
Regarding his powers, from the little we manage to understand, they seem to be able to manipulate the luck, so to influence directly the Fates, along choosing which timeline(?) we will be using the odds(?).
Basically, a Wonder of Luck or Fates.
