Swarm · 1 hex · SM +0 Swarm of Insects [Monsters on Automatic, SRD coverage: swarms; answers Swarm of Insects (SRD 5.1)]
Whatever the region breeds — hornets, biting flies, ants boiling up out of the ground. It does not care about armour and it cannot be frightened off, and the party's spellcaster is going to have a much worse time than the party's fighter.

Notes
- GCS ancestry draft: gcs/swarm-of-insects.gct
- Independent build total: -37 points of racial traits plus 0 points of racial skills.
- Answers the SRD heading(s): Swarm of Insects (SRD 5.1). Only the creature identity is taken from the SRD; the GURPS statistics, ratings and prose are this project's own work and reproduce no SRD text.
- Typical Stats, damage and ratings are derived from the racial template, not authored beside it, so the sheet and the stat block cannot disagree.
- Body mass used to scale this build: 5 kg. ST, Size Modifier and DR are checked against it; see the gurps-animal-sanity-check skill for the bands.
- Movement: ground Move 3; air Move 11 (primary). The published Move is the primary medium's cruising Move; sprint figures are stated here and not folded into it.
- Treasure and grappling are not authored for this batch and ship as explicit nulls; `lair` carries a short habitat note, because where a wandering animal dens is an encounter fact rather than a loot one.
- One hex, and deliberately generic: the SRD heading covers whatever stings locally, and the mechanics are the same either way.

- Description
- Written by Dungeons on Automatic, released under cc_by_4_0
- Independently authored GURPS build. The SRD supplies the creature identity this record answers to and nothing else: no SRD statistics, wording or presentation is reproduced, and no third-party GURPS conversion was used as an input.
- Answers the SRD heading(s): Swarm of Insects (SRD 5.1).
- Racial template: -37 points across 14 traits, plus 0 racial skill(s) worth 0 points.
- Every trait is drawn from the project's controlled GURPS vocabulary in scripts/srd/trait-library.mjs, which carries the page reference and published cost for each entry.
- sourceSystem is recorded as doa_fixture because that is the package contract's value for project-authored material; the SRD headings this record answers are in provenance.coversSourceIdentities.
- Ratings are recomputed through the consumer CER path on every build, so a mechanics change cannot leave a stale rating behind.
