"Hunting the Firehawk" is a story mission in Borderlands 2
How to start
Speak to Roland
TURN IN: Lilith
Money and XP
In order to defeat Jack, you will need to find a soldier named Roland. He's gone missing, but you have one lead: a fearsome bounty hunter, known as the Firehawk, summoned Roland shortly before your arrival. If you can find the Firehawk in Frostburn Canyon, maybe you'll find Roland, too.
Lilith, alias "the Firehawk," has informed you that Roland was kidnapped by the same clan of bandits that invaded her lair. You'll have to rescue him.
