Wildspace

Wildspace refers to the vast, empty void that exists between the celestial bodies within a fantasy cosmology, most notably in settings like Dungeons & Dragons. It is not truly empty but rather filled with a thin, breathable atmosphere that allows for interstellar travel. Planets and other solid celestial bodies are suspended within this expanse, often with their own inherent magical fields that maintain their atmospheric envelopes.

Travel through Wildspace is typically accomplished by means of spelljammer ships, which are vessels specifically designed to navigate the void. These ships are often powered by magic, such as helms that allow a spellcaster to mentally propel the ship. Gravity on these ships is usually artificial, created by the ship itself or by magical means, rather than being inherent to the vessel.

The concept of Wildspace distinguishes it from planar travel, which involves moving between different dimensions or planes of existence. Instead, Wildspace is the substance of the universe itself, the space in which stars, planets, and moons reside. Navigation within Wildspace can be perilous, with potential dangers including asteroid fields, strange nebulae, and hostile creatures adapted to the void. It is a realm of exploration, trade, and adventure for those brave enough to venture beyond the confines of a single world.
