I’m writing (more) fanfic.
How human are Heralds of the various Eternals?
Not so much in terms of physical structure (If you cut them in half would you see organs or fizzing energy of their Realm?)
Not so much in terms of adherence to a human form (it’s a fish! a bird! a skeleton! a rabbit! a small plushy whale! a patch of grass!)
But in terms of emotional depth and range. In terms of mind and/or soul. In terms of Free Will.
I’m guessing that they vary from almost human to almost a small copy of their Eternal, possibly as a reflection of their power level. So at the top level, you’d be wondering if they aren’t actually a puppet of their Eternal, while at the lower level it’s almost human except for a few quirks (I imagine no Herald of the Whisper Gallery, for example, could tell you a secret if it wanted to…).
A Herald on a mission at Anvil would do its best to achieve it’s mission, but do they then have the free will to, for example, go and collect information useful to their Eternal on the way out? Stop and check in on other interests? Go for a drink in a Highguard bar just to wind them up? (probably not, unless there’s an Eternal of annoying Highguard) Pick a fight because that last mission left them in a foul mood?
They generally don’t in-game, as you want that NPC and crew member back to do the next 15 things, but would they in setting?
Can they (individually, and not as a representative of their Eternal) be offended, interested, repulsed, or attracted…
Can a Herald fall in love?
It might be that this is stuff to be explored in play. It might be that this is below the abstraction layer (although it’s known IC), and so hasn’t been written up on the wiki because frankly, it’s not that important . It might be that no-one’s thought about it (Hah!).
But given their appearance on the field and in the fluff over the years, I’m guessing that most of the Heralds we (IC) see are pretty human in outlook…
Beyond mortal ken, file 65
"…after extensive divinatory rituals, we discovered that the crystal was in fact a Herald of Adamant. After three weeks of attempting to decipher the careful chimes and resonances that it was emitting, we decided that it was in fact speaking in a non-linear language about a subject outside of our frame of reference, but possibly to do with the structure of matter at either a very large or a vary small scale.
With an apologetic note, we therefore sent it back to Adamant."
