The SRD 5.2.1 is licensed under the Creative Commons Attribution 4.0 International License, available at https://creativecommons.org/licenses/by/4.0/legalcode.

Identified SRD Material
The following names are sourced from SRD 5.2.1 for their use on this website:

First World: Feywild, including use as a planar name, alternate name, page heading, subtitle, navigation label, catalog entry, or encounter label such as “Feywild Encounters.”
Shadow Plane: Shadowfell, including use as a planar name, alternate name, page heading, subtitle, navigation label, catalog entry, or encounter label such as “Shadowfell Encounters.”
Heaven: Mount Celestia and Arcadia.
Elysium: Arborea and Ysgard.

The names “Feywild” and “Shadowfell” are reproduced from SRD 5.2.1. Their placement within d20Gen's interface and their combination with interface wording such as “Encounters” are d20Gen's editorial adaptations. These labels identify the SRD-derived names; they do not designate the surrounding encounter content or setting lore as SRD material.

Source and Adaptation Notice
These names appear in the planar tables on pages 209 and 215 of SRD 5.2.1. d20Gen has selected and arranged them as alternate labels and cross-references within its own navigation and encounter tools. Their association with the pages listed above is d20Gen's editorial arrangement; it does not assert that locations from different settings are canonically identical.

Material covered by the Open Game License, the ORC License, or Paizo's Community Use Policy is governed by its respective notices and permissions.
