Good question. I should have supplied this earlier.
Our game world is set right at the end of the Roman Empire. (In a "rome" that has Elves, Dwarves, magic etc.)
Katyos is a Pictish Spirit Shaman. Pictland, aka Alba, is at the north-eastern portion of what is today called Scotland.
The Picts are ruled by a warrior queen, and have been in an ongoing conflict with the Scotts over territory. They have a long historical conflict with Rome, as represented currently by the Breton, south beyond Hadrian's Wall, past Scot territory.
So, although he travels with a few Scots and a couple of Breton, he has a deep seated mistrust for both groups.
The civilized world has received a warning of an oncoming army from the east, starting in Mongolia and rolling towards Europe. They carry/use the black plague as a weapon, a plague that for some reason the Orcs who make up that army appear to be immune.
World history, and recent evidence suggest that there may be a draconic influence behind all of that.
While it pleases Katyos no end that Rome will be overrun, the hard fact is that his homeland will fall as well. To prepare for that war, which may be years away, the various nations need to cease fighting between themselves and prepare.
So, for some time now, we've been pursuing a peace with Rome, which still holds some sway in Britania. That peace will involve both the Scot and the Pict.
Katyos is more than a little conflicted over this. So, for that matter, is the Pict Queen. Her heart says that war trains men for war, and that the territory could present a united face to an enemy if she conquered the Scots. Her head knows that won't happen in time.
Katyos feels the same way.
Our version of "working for peace" to date involved fighting our way south towards Londinuim, to rescue a royal emmissary who was kidnapped before he could deliver the peace proposal, and sold into slavery. From there our path lead to the Isle of Man (in the Irish Sea, between Ireland and Britain), to north Africa, to Egypt, and now into Hijaz, which is an ancient province/kingdom in what is today Saudi Arabia.
The enemy have been using undead and draconic agents.
Our current location, if it makes a difference, is in the Arabian desert, approaching a necropolis, a city of the dead that was all but swallowed by the desert sands.
Katyos' personal interest involves speaking to the spirits he encounters and helping them find rest.
That give you something to work with?
