This is a transcript of my piece in Episode 97 of our podcast, on The Emissaries. It reveals spoilers for the Mercy of the Icons campaign, if you are a player and don’t want to be spoiled, read no further.

If you can level one criticism at the Core book in Coriolis, it’s that it teases you with, seemingly, a million snippets of lore that it doesn’t explain fully. Most of these are fine, I have imagination enough to make something up, and indeed some of those snippets have provided inspiration for pieces on this very podcast.
But one bit of lore left me, and I expect, a lot of other readers very confused. Who, or what, were the Emissaries? In this piece I am going to answer that question, drawing exclusively from the published books, not adding any of my own ideas. The first we read of the Emissaries is in an extract of THE REALM OF THE ICONS – A HISTORICAL OVERVIEW OF THE THIRD HORIZON by Kaldana Mourir, quoted on page seven:
“Zenith heralded the dawn of a new era – and the Horizon blossomed once again. Three dozen star systems, linked by fate and by the will of the Icons, wandered together towards a brighter future. But as the Emissaries arrived, the happy days drew to a close, and the Dark between the Stars slowly came creeping back.”
The Emissaries are a BAD THING then, or at least they are in the eyes of Mourir, who is obviously a Zenithian apologist. Perhaps the Firstcome see them as allies? Perhaps not, because on page 13:
From the depths of the gas giant Xene rose the faceless Emissaries. Spectres from another world, Icons or Portal Builders? The theories about their origins are many. The Emissaries demanded a seat at the Council – and got one. One of the Emissaries claimed itself an incarnation of the Icon the Judge, to which the Order of the Pariah cried “sacrilege!” and closed their home system to all travel. A new age of shadows and suspicion has dawned, and the peoples of the Horizon all wonder: what is the true agenda of the Emissaries?
I think it was at this point, with their description as “faceless” that I started to imagine them as the Vorlons from the TV show, Babylon Five. On page 184 they are described as “ghosts from another world.” And, indeed on page 240 is says “often described as either spirits or spectral phenomena”. Often described? So, rarely actually seen it seems. And mostly spoken about in rumour. We are not even sure how many there are: “rumors claim that there are really nine altogether and that the Foundation and the Consortium are hiding the truth.”
But we know about only five of them, three of whom are out and about, location unknown, ready to meet your adventures whenever time, and story are right. This I like, we don’t need to pin them to a place your players might never choose to visit. One remains on the Foundation station orbiting Xene, now a place of pilgrimage, because that one claims to be the icon the Judge. The fifth is on Coriolis itself, as a (non-voting) member of the council. And one has to ask, what power do they have that one can “demand a seat on the Council”, and get it?
Talking of powers, we also know that people only started manifesting mystic powers when the Emissaries appeared. Obviously the two phenomena are connected, but how?
Moving on to the Atlas compendium, the back cover teases “the true nature of the mysterious Emissaries [has] only been myth to the common people of the Third Horizon – until now.” But does it really deliver?
It does explain the war between the Terran Empire of Ardha, and the Symmetry of the Second Horizon, which is known in our Third Horizon, of strategic value to both sides, as the Portal Wars. It also describes (on page 23) nodes: “A node can create a mystical and physical link between systems in a fashion that falls outside of the technology and methods used by the Portal Builders.” Nodes were created and destroyed during the portal wars as the First and Second horizons used the Third to attack each other. Eventually most were destroyed. But one survives on Xene, a weak point in the Second Horizon’s defences.
On page 25, the Compendium describes how, when a prospector ship made an emergency landing on Xene, mystics of the Second Horizon possessed the crew. Or tried to at least. Only one crew member was successfully taken over, with the mystic in the Second Horizon managing to retain her identity as she took over her host. That one is the one that now sits as an observer on the council. The other four (or eight?) were affected to varying degrees by the Darkness between the Stars.
So, not Vorlons after all, or Faceless, or even “described as […] spirits or spectral phenomena”- they look human it seems… except … in the book Coriolis: The Art of the Third Horizon there is an image captioned, The Spirit of the Emissary. It shows a cloud of fractal light and darkness above a writhing human on an altar or bed, so perhaps some people can see the Emissary as a spectral phenomenon in certain circumstances.
Most people can’t though, because we can witness actual possession if we play A Song For Jarouma, from Emissary Lost (page 228): “Mid-argument, or on their way to the next installation, a person believed to be dead or dying suddenly comes to life. With a spasmodic jerk and a terrifying scream, the team member tumbles onto the floor. Then, equally suddenly, they stop spasming, and stand up slowly. Looking around, they nod and blink, confused. They look like they are uncertain of their whereabouts (the person has been taken over by an Emissary.)” No mention of fractal clouds there. In that adventure we create the true story behind that prospector ship making an emergency landing. (It turns out not to be prospectors, and not quite the sort of emergency that the Atlas Compendium suggested.)
Emissary Lost has more to divulge about the Emissaries. It turns out they are Santulans, the highest ranking mystics in the Second Horizon. They introduce themselves to the people of the Third Horizon as “The Light of Peace” but whether they are remains to be seen.
