Mordecai's Foul Concoction [Contains Spoilers]
You return to The Keep, weary and travel stained. Many days you have been gone, and the sight of home is a fond one. A swim in Lake Lakira, a cold drink at Remy's - but first you must complete your task. Without stopping to bathe and dress in fresh clothing, you continue straight to Thane's study. You knock on the scarred wood of the door, and it swings open, revealing Thane behind his desk. His face rests upon his hand, dark with worry. He rises as you enter, and with care you open your bag, taking out the herb. Wrapped in silk to protect it from the journey's hardships, you hand it to Thane, hoping you have arrived in time. The High Archmage lets out a deep sigh, a smile creasing his face. He looks up at you, and says, "I thank you. I feared the worst. Now," he said, turning from you, "I believe we should make our way to the hospital wing," and he hurried from the room with the herb, leaving you to follow after.

Lying unconscious in a bed is a man you recognize; Alchemist Castorz. He is the most skilled and practiced magi at brewing potions, able to create a draft in half the usual time. He is a great teacher, and you feel a pang of remorse at having helped injure him. You watch as Thane leans over him, dropping a single leaf into a brew. With only one sip, Castorz begins to revive, his pale skin turning healthy, eyes fluttering beneath lids. With another sip, the man returns to consciousness and is sitting up, blinking. Thane slumps back in his chair, catching your eye and smiling.

Castorz looks around and spots you, gray eyes full of warmth. "Is this the student that is responsible for my recovery?" he asks, voice full of approval. You nod, aware of your role in this man's illness. Struggling to rise, Castorz stands, pushing Thane away. "Come with me," Castorz says, beckoning. You follow him, amazed at his sudden recovery.

He leads you to his study, and the begins rifling through his things, displacing odd bits of parchment and essays, finally finding what he was looking for. "Such bravery deserves recognition," he says solemnly, presenting you with a bundle of cloth. "Not many your age would take on such a quest."

Smiling, you take the parcel, gently unwrapping the package, revealing an egg like none you have ever seen. A tiny green wing has unfolded from the egg, soft to the touch. You hold the egg gently against yourself and make your way upstairs, full of pride at being trusted with such a rare creature.
