Ashlar is the planet the Oberon crash-landed on.
One billion years ago, comets bombarded on Ashlar, causing great pain to the dominate lifeform - Great Nest, a species of brachipods controlled by a insectile hive-mind known as the Core. This leaves the planet covered in massive craters that, over time, form mountainous valleys.
This was revealed in Planet of the Apes: The Fall.
