Galg (Galg I-1)

Galg is a rocky planet in the Galg System and is technically labeled Galg I-1, being the first moon of Galg I, commonly known as Galgam. Galg is the home of the Galgo, the dominant civilization of the system, and due to this and the fact that it is a moon barely small enough to avoid being a binary planet, Galg is usually spoken of as a planet itself. It is roughly the size of Earth's moon, and twice as dense. Galg's surface is fairly flat, with shallow seas and low mountains. Due to its nature as a moon of Galgam, tidal forces affect a significant surface area about the planet’s rotational equator, with vast plains being submerged and revealed each day. This has led to strongholds being built on the higher regions of these latitudes, and roads being feasible only further north and south. These tidal forces also affect the atmospheres of Galg and Galgam, to the point where air is noticeably thinner at low tide and there is even enough atmospheric pressure between the planets that the region in which there is a practical vacuum is thin enough to be traversed without an absolutely airtight ship at high enough speeds.

Ecology
Most of the tidal regions are dominated by a tall, amphibious grass that is fairly stiff when dry (somewhere between wheat and bamboo), but when submerged by the extreme tides, it soaks up water and almost doubles in length, becoming much more flexible. It has small, air-filled seed pods that are held up by the dry, stiff stalk, but will float the wet plant up to where there is more sunlight. The standard beast of burden on Galg is a creature most comparable to a giraffe, although it has a more forward-facing neck, much longer legs, and walks rather like a spider. It is able to traverse the tall grasses of the equatorial tidal plains at significant speeds (during low tide), and is fast enough to make it between distant island/mountains in a single low tide. They can also wade a good distance into the high tide for fishing, both for its own food and for the Galgo who have trained them. The fish on Galg either are carried along in the tidal swell and thus circumnavigate their globe daily, or live in valleys deep enough to be perpetually filled with water.
