# Campaign > Kinbarrow modding reference — content tree `b2f73c2ab65ff925`, version `0.2.0+main.a22009f4c`. `campaign.ron` — the manifest. `id` equals the campaign folder name. **Note on syntax:** these files are RON, not JSON. The shapes below are exact, but punctuation follows RON — read a real `data/*.ron` file alongside. ## Fields | Field | Type | Required | Description | | --- | --- | --- | --- | | `chronicle` | `Note[]` | required | Backdated chronicle entries the world opens with. | | `death_day` | `uint64` | required | The day the campaign's founding death fell (the ducal assassination). | | `default_seed` | `uint64` | required | Root of every deterministic roll when no seed is supplied. | | `description` | `string` | required | A one-line blurb for the realm (flavour, not resolved). | | `id` | `string` | required | | | `name` | `string` | required | The realm-scale region the towns sit in ("Thornwood Vale"). | | `player_start` | `PlayerStart` | optional | Where an admitted player character comes ashore — the creator's data. Additive: a campaign without it can still be played through the seeded pregen fast lane. | | `roads` | `Road[]` | required | Roads laid AFTER the towns are built, resolved by node name. | | `slots` | `Slot[]` | required | Procedural town slots (worldgen) — what makes the realm the realm: an authored coast plus a generated vale. | | `source` | `Source` | required | | | `start_day` | `uint64` | required | When the campaign opens (day, and the hour the world boots at). | | `start_hour` | `uint64` | required | The hour of `start_day` the world boots at (0-23). | | `towns` | `string[]` | required | Authored towns, by file id (`towns/.ron`). Sorted at load, so the interpret order never depends on filesystem iteration order. | ## Nested shapes ### Note A backdated chronicle note (`record_at`). | Field | Type | Required | Description | | --- | --- | --- | --- | | `day` | `uint64` | required | The day the note is backdated to. | | `hour` | `uint64` | required | The hour of that day (0-23). | | `text` | `string` | required | The chronicle line's text. | ### PlayerStart Where the character creator's minted PC ENTERS the world: the settlement it comes ashore in, the venue/ward it is placed `LocatedIn`, a starting purse, and an optional ward membership. Resolved BY NODE NAME at admit time (the interpreter has already minted these), so it reads like the campaign's roads (also name-resolved). Validated by the one campaign validator (`campaign/validate.rs`): the settlement, venue, and ward must name real nodes the town declares. | Field | Type | Required | Description | | --- | --- | --- | --- | | `level` | `uint32` | default `1` | Starting character level for chairs that come ashore in this campaign. Absent/default 1. Capped at the creator's current maximum (Battle's picker uses the same door). A campaign that wants to skip the dull rungs sets 3. | | `purse` | `integer` | optional | A starting purse in the coin good's minor units (silver), if any. | | `settlement` | `string` | required | The settlement the PC enters (a town's display name — "Greyharbor"). | | `venue` | `string` | required | The venue OR ward the PC is placed `LocatedIn` — "The Brined Gull". | | `ward` | `string` | optional | A ward the PC joins on arrival (`MemberOf`), by name, if any. | ### Road A road between two named nodes, carrying the ride's length in days. Resolved by node NAME after the towns exist. | Field | Type | Required | Description | | --- | --- | --- | --- | | `days` | `int64` | required | The ride's length in days. | | `from` | `string` | required | The node the road runs FROM, by name (a settlement). | | `route` | `string` | required | The route's display name ("the Coast Road"). | | `to` | `string` | required | The node the road runs TO, by name (a settlement). | ### Slot A procedural town slot: worldgen builds it, and a road binds it to a settlement that already stands (authored, or rolled by an earlier slot). | Field | Type | Required | Description | | --- | --- | --- | --- | | `days` | `int64` | required | The road's length in days. | | `kind` | `SlotKind` | required | What procedural fill this slot requests. | | `road_from` | `SlotRoad` | required | The settlement this slot's road runs from. | | `route` | `string` | required | The road's display name. | ### SlotKind The kind of procedural fill a slot requests. #### SlotKind::Worldgen A full worldgen town, landlocked farm-and-forge by default. #### SlotKind::Mountain The far mine-and-mithral peaks: a mountain town whose data `mine` instantiates the rare-regional mithral deposit — the first world where mithral flows. Booted only at three towns (RPGPT_TOWNS=3). ### SlotRoad Where a slot's road runs FROM — the settlement at the road's other end. Two forms, because a realm's towns are not all named at the same time. An AUTHORED town has its name in the campaign's own files, so a slot can just say it. A ROLLED town's name is drawn from the realm seed at compose time and does not exist while the manifest is being read — so a road that runs from one must reference the SLOT that rolls it, by index. That second form is what lets a wide realm CHAIN (the river town off the vale, the high pass off the river, the forest past the pass) rather than starring every road off the authored coast — which piled every route posting and traded store onto one hub and grew its menu enumeration superlinearly in town count. #### SlotRoad::Town An authored settlement, by name: `Town("Greyharbor")`. Carries `string`. #### SlotRoad::Slot A town of the COMPOSED realm, by index: this campaign's root town is `Slot(0)` and slot `n` is `Slot(n + 1)`. It must already stand — a slot cannot road from a town placed after it. Carries `uint`. ### Source Every file's top-level value carries `source`. #### Source::Srd51 SRD 5.1 — retained nonconflicting catalogue material. #### Source::Srd52 SRD 5.2.1 — the 2024-revision System Reference Document, the same CC-BY-4.0 grant as 5.1 and the current rules chassis. Its files carry the `.srd52.ron` suffix so provenance reads off the path; see `data/README.md` for which document rules a given value. #### Source::Original Original content authored for this game (not from the SRD). #### Source::Phb2024 Material transcribed from the 2024 Player's Handbook.
