Alright, so here's some half-assed faction related stuff. This seems to cover everything important short of most of the actual events, plus some of the aftermath.
PARASOL INDUSTRIES
First seen in Syrupleaf, they make all kinds of things just to see if they can. In essence, they are the spirit of dwarven !!SCIENCE!! made manifest! Some of the less tech-savvy among them may have turned bandit in the wake of the portals being closed.
Some dwarves may be descended from stranded Parasolians, and carry some of their parents' knowhow with them.
BALLPOINT TECHNOLOGIES
A mercenary and weapons R&D company, they were a major antagonist in Spearbreakers' lifetime. The bulk of those left behind in the wake of the battle of Spearbreakers turned to banditry, though some are found among human and dwarven settlements, generally employed as militia members.
BioScience branch of R&D responsible for infectious Spawn and procreating vampires.
STONE Inc., Aegis Operations, and Nemea
Lesser factions involved in the fields of weapons, armor, and security. STONE supported Ballpoint in the war against Eris, while Nemea supported Eris (under contract,) and Aegis assisted both sides in R&D. Nemea may feature as a hostile entity.
SEWATURET
Human city-state faction aligned with Ballpoint, had a hand in defeating Joseph.
ERIS
"Small-time" corporation fighting a war against Ballpoint Technologies and Parasol Industries. Accomplishments include turning the two companies against eachother via hiring Ballpoint through a proxy. Ultimately destroyed by combined efforts of multiple parties and plain old bad luck.
SCYTHOD
Alien race that wanders the world, accidentally introduced to Everoc by Ballpoint. Highly predatory, though some tribes have formed amicable trade relations with sedentary races by selling animal and fish products for water and raw materials. [MAY OR MAY NOT FEATURE IN SBII AS CIV.]
SEQUIVET
Strangler-like race from beyond the stars. Solid warriors and spies. Very skittish, very unwilling to communicate with locals directly. [MAY OR MAY NOT FEATURE IN SBII.]
THE RESPONSIBLE OUTRAGEOUS FENCES
Dwarven civ to which the dwarves of Spearbreakers paid allegiance to. Lead by a Queen Sibrek during the Time War. Noted for its use of "short pikes" in its military over spears. Has a literal Iron Palace in the Underworld.
DISCIPLES OF FISCHER
Dwarven Knighthood Order, established after the passing of Col. Fischer. They often maintain chapter houses in counties and higher rated dwarf lands. Scary people.
SONS OF DAUROS
Dwarven Knighthood Order, established following the passing of Col. Dauros. They often maintain chapter houses in baronies and higher rated dwarf lands. Also scary people.
ONOL-KOR
Former residents of East Everoc. Old version called Mountain barbarians. Culture centered around raiding, fishing, and fighting the Spawn> Cannot be raised as zombies, and blood is said to smell of burnt bacon.
