Percy Jackson and the Olympians: Legends

The Wolf House is a place where Roman demigods and legacies start their demigod journey. It is there where Lupa judges whether or not the demigods left there are worthy and strong enough to endure her training. If so, she adopts them as her cubs, like she did with Romulus and Remus, teaching and conditioning them until she judges them worthy of taking their place as Legionnaires of Rome. Then she gives them directions to Camp Jupiter leaving them to fight their way there alone; conquer or die.
