The Ultimate Battle is a solo mission you can after the Large Man in Vancoor Square cutscene. It was intended for Elwen, but she asks Jack Russell to handle it. Outside of Echidna Gate you fight Ursula's golem Melissa.
Chief Elwen, the time has come for you to prove your strength. Do you dare challenge my golem to a battle?
To recruit Ursula you have to complete The Ultimate Battle and The Real Ultimate Battle, then talk to her.
