A Satyr's Sanctuary is a magical blessing that is bestowed by satyrs. It allows wild animals to retrieve whatever they need (food, water, etc.) until they find a safe place to live.
In Las Vegas, Grover Underwood performs a Satyr's Sanctuary on a zebra, a lion, and an antelope, that he, along with Annabeth Chase and Percy Jackson, free from a smuggling business called Kindness International. By doing this, he grants the animals protection, and assures that they are able to find food, water, and shelter until they find a safe place to live.
