The Veilfen is a broad fey marshland surrounding Mirehollow, where waking reality overlaps with a mutable dream world. Blackwater channels divide reed seas, drowned forests, and floating islands large enough for villages. Luminous plants illuminate paths that do not always remain paths, while independent reflections and early-arriving sounds make every journey uncertain. The region remains explorable because wardens mark reliable routes, travelers can anchor memories with tokens, and Dream-Tide effects intensify gradually rather than striking without warning.
