Medic Hawthorn, outside of Valiance Keep, wants you to go inside the Stormbreaker's hold and retrieve Hawthorn's Anti-Venom from a crate of First Aid Supplies.
You there! Please, I need your help. This soldier will succumb to the cryptfiends' venom unless we act immediately.
I've managed to slow down the poison, but without a suitable supply of antidote I cannot counteract it.
I was promised a new shipment of anti-venom in the Stormbreaker's most recent trip from the south. Go inside its hold and search for a chest of first aid supplies.
Hurry, [class]! We can't afford to lose any more men unnecessarily.
