Getting there
Mirabel's search for a treatment sends the player toward the Grand Arena, where William provides the background of the dragon and helps explain how to enter the encounter.
Purpose
The encounter supplies Dragon's Breath needed for Everdawn's medical investigation. Ignevar can be challenged again, including for additional bottles of Dragon's Breath.
Lore
Story spoilers
William recounts his family's long history with Ignevar. His grandfather exploited that relationship and left the dragon under a deadly final command. This history gives the arena fight a more personal background than an ordinary dragon battle.
