The terrain on Alder is quite distinctive in some areas. Most of the terrain is ice and glaciers covering the planet, but there are some mountain ranges on the planet with hot springs and caves. There are also some oceans on the planet with a different variety of sea animals.

Discovery
The planet was discovered around 40 BBY by several Republic explorers. They did excavations and mining operations seraching for valuable crystals. Eventually the mining operations were shut down and the planet was abandoned.

Clone Wars
By 19 BBY the CIS had taken control of nearby systems and were planning to invade Core Planets. The Galactic Republic decided to place clone troopers on Alder, not only for defense of the Core Worlds, but also because of the planet's strategic importance. As the Clone Wars entered its final month, the CIS attacked the planet, and the result was an enormous battle.
