Tiers are a term used in the Storytelling System to denote different "levels" or styles of play. Originally introduced in the Hunter: The Vigil Rulebook, it was quickly expanded to cover other systems.
This is the lowest, most personal tier, dealing with individuals and troupes, with little going beyond. A political organization is little more than a gang at this level. It's the level of the locality.
This is the mid-level tier, and typically the default assumption for most games, operating at a city level. While individual tier 1 groups may move around, their actions are typically part of the grander designs of tier 2 organizations.
- Vampire: The Requiem: ancilla/Covenant
- Mage: The Awakening: Consilium
- Hunter: The Vigil: compact
This is, for most purposes, the top-level tier. It covers national or even global-level politics and conflict, with PCs being major movers and shakers within their societies.
- Vampire: The Requiem: elder/conspiracy
- Mage: The Awakening: Order
- Hunter: The Vigil: conspiracy
