Jewel Beast

Story
The Jewel Beast is a monster created when Saruin implanted Fatestones of his own into a monster, it gained substantial power and the ability to use magic from each element. Saruin couldn't control it, so he sealed it away in the Frontier in a deep sleep.

The Jewel Beast's awakening is determined if one clears the frontier quests early. By defeating all the fixed encounters in each quest the Jewel Beast's awakening will be delayed. Getting to it's lair involves clearing the Assassin's Guild quest first as Strife will mention the Jewel Beast.
