First of the Sun
The First of the Sun page gathers its physical environment, climate, biosphere, habitats and unresolved research questions.
- Planetary system
- Drominad system
- Physical scale
- Ocean-rich island planet with at least one moon

Geology and terrain
An archipelago world with one major continent
The planet has a mainland, many home islands and a separate archipelago of roughly forty islands. Beaches, cliffs and dense interiors create strong local variations.
Climate and atmosphere
Maritime climates and dangerous island weather
Known settlements experience ocean-moderated conditions, while the Pantheon is more isolated and unpredictable. Wind, salt, storms and fresh water shape the coast.
Biosphere
A bird-rich ecosystem with extreme predators
Native birds occupy many ecological niches, while the Pantheon contains unusually dangerous flora and fauna. Isolation has allowed island ecosystems to diverge.
Habitats
Home islands, coasts and restricted interiors
The home islands support settled coastal communities and cultivated land. Pantheon's beaches may be accessible, but its interiors are hostile to sustained habitation.
Open questions
An ecosystem observed from the edges
The full number of island species, the Pantheon interior and the oceanic food web are still largely unknown.
