Lord of the Mountain

The Lord of the Mountain is a spirit in the Legend of Zelda: Breath of the Wild. It is also known as Satori. Sometimes there will be a green light from Satori Mountain. Head there and you will find the Lord of the Mountain surrounded by Blupees. You can use Bomb Arrows to get a lot of Rupees, or sneak up on Satori to ride it and obtain the Ancient Bridle if you have the DLC. Unfortunately, you cannot register the Lord of the Mountain, because the stablefolk think that it is cursed.
