Sandboxes tend to imply factions, but faction play is sometimes a boogeyman for open world games. Should it be subtle, just a thought? Should it be a tracked rubric of needs and wants, like a private rumor table with bonuses? Should it be a complex system of rolls and resources, like a solitaire Matrix game the referee plays behind the screen on off-hours? Well, it ought to be something if merely to add some variability to whatever sociopolitical forces prop up the flavor of the setting.
Stars Without Number is often the poster child for robust faction play, and for good reason. Multiple spreads from that big book are spent detailing what and how many resources any faction has, its stats (typically reach, cash, influence, brute force, etc), and the various tags that allow it to flex various faction moves on other factions who are also using faction moves against yet more factions. It's robust, yes. It's also rather crunchy for my taste. Resources and stats and tags are tied to numbers which influence rolls which limit or expand the scope of possible actions... If you want to spend an evening setting up the big players in a space opera and roll dice back and forth to generate a whole sector's worth of complex action and intrigue, look no further than SWN's approach. A lot of brainfuel, but hold up, Kevin Crawford, you've developed an entire minigame here.
Somewhere more in the sweet spot for my taste is Mausritter's setup. Personally, I prefer a tiny bit more detail on each faction write-up and its derivative elements, but this is a solid foundation. You have the following full procedure (copied from the free PDF for clarity):
|Go play Mausritter.|
|Go play Master of Orion.|
While there are many actors in the Dolmenwood setting, I've identified ten major factions which have enough persistent influence and resources to be major players in the sandbox. As such, I've identified them below, along with the Mausritter-adjacent treatment. Note that these are my write-ups for my live home game, personalized for that table's instance of the setting, and are neither fully representative of official Dolmenwood "canon" nor any of my online games. As always, plunder as is useful to you.
1. The Church of the One True God
Seat of religious power in the Wood. More a cult of saints than a traditional monotheism.
- Dozens of specialized clerical and monastic orders, all playing to different strengths

*While this is a catch-all category, I see some actors (like Lady Harrowmoor [human] and Lord Murkin [goat]) as more prominent than their lesser peers, but not as much as, say, Brackenwold, Ramius, and Malbleat.
- The Upper Hemeth floods, disturbing Lake Longmere and all points northwest. Fishermen around the Lac find strange squids and chunks of half-floating black stone, smooth on all sides.
- A forest fire rips through the woods between Dreg and Lankshorn, as well as igniting a good bit of peat in Hag's Addle. A few dozen cottagers are displaced and a fell stone is revealed in the ash.
- After days of loud moaning, the bicorne southwest of Lankshorn attracts a mate from west of Kolstoke Keep. The two are spotted mating and spawning offspring faster than should be possible.
- The largest towering fungi around Orbswallow begin to ambulate, dragging sloughs of decay and airborne mushroom funk out of Mulchgrove to the Aldweald on an unwavering path directly towards Prigwort.
- Rain ceases to fall over the Tithelands for a month. Castle Brackenwold and High Hankle slip into a recursive supply chain crisis and the farmers in the fields, hungry and without work, harry trade.
- Unseasonal snowfall blankets the Dwelmfurgh and out across the center of the Ardweald. Panic sets in as commoners won't stop associating the grasp of winter with the pending return of the Cold Prince.
- Toll officers and their hangers-on throw off the rule of Brackenwold and setup Fort Vulgar as an independent garrison town. Extortion of local travellers quickly sets in and becomes a constant problem for trade.
- Bishop Jospher Sanguine is murdered in broad daylight within Castle Brackenwold. Witch hunts, both literal and figurative, run rampant in the duchy while petty squabbles delay new leadership in the Church.
- Dozens of brigands, sellswords, and rogues flood in from the Tablelands, quickly taking up residence in Drigbolton and transforming the sleepy hamlet into a hive of scum and villainly rivalling Dreg.
- Urged by his new wife, Baron Hogwarsh whips High Hankle into new heights of order and vigil. Lords Ramius and Malbleat are belittled by Hogwarsh's authoritative push into the High Wold. Rumors say Baroness Hogwarsh is a witch!
- A freelance adventuring party, "Victorious Secret," sets up shop in Meagre's Reach, transforming the bizarre bumpkin village into a hub of activity, profit, and rumor-mongering. Mercenary companies are frustrated by their success.
- The every-so-often hunting party under Duke Mai-Fleur decides not to leave Dolmenwood following their last foray near Mulchgrove. The Duke declares that the eastern half of the Wood now belongs to him as private property.
- A new drug, "Goblin Mung," becomes very popular across the Wood. Production and refinement of other reagents and alchemical substances halts as this new "cure all" and mild hallucinogen supplants all competitors.
- Dozens of riding horses across the Wood transform into oversized black unicorns with hulking musculature. They impale their handlers and nearby innocents, then race off to the northern forests with a keening, maniacal cry.
- The entire town of Odd disappears. No one notices. What people do notice, however, is when it reappears a week later on the roof of Duke Thespian's residence in Castle Brackenwold. Assumptions point to fairy mischief.
- For four days the sun does not set over Prigwort. The rest of the Wood proceeds normally, but once the moon finally reappears over the city, many locals begin acting like wild animals, while many wild animals begin acting like locals.
- Following a convergence of two constellations, Ardbeg's Crook and Donager, a curious, hollow monolith appears within the fungal forests of Mulchgrove. Local moss dwarves who enter it do not exit again, leaving many concerned.
- Fire falls in a searing pillar from the night sky into Lake Longmere. When it departs at daybreak, a huge marble-like egg hangs twenty feet above the water's surface, inscribed all over with patterns of snakeskin, fangs, and slit eyes.
