Lore Books & Expansions

Each Lore Book represents one era: P, M, V, PM, Mo, A, S. Lore Books add era‑specific classes, items, hazards, maps, and at least one campaign arc.

Era Symbols & Legality

  • Items and options carry Era Symbols.
  • Use only the era’s symbols unless an adventure explicitly allows cross‑era play.

Expansion Types

  • Lore Books (Major): full era rules + campaign arc.
  • Story Packs: focused story arcs inside a Lore Book.
  • Item Packs: gear/crafting trees; require the parent Lore Book.

Custom Lore Rules (Examples)

  • Primal: durability, tribes, relic expeditions.
  • Medieval: sieges, oaths, fealty vs tyranny.
  • Victorian: news cycle, industry, patents.
  • Post‑Modern: total war and propaganda.
  • Modern: cyber operations and surveillance.
  • Apocalypse: scarcity pressure.
  • Signalfall/Space: zero‑g and signal drift.
