A letter would arrive addressed to Hyssir'larhaa Aardynar.To the Karl of Friedaelt,
Good Day Sir Hyssir'lahaa. After talking the matter over with my Alchemy Master, she has assented to your generous offer of instructing me in Virology. If you need anything in return for your instruction, be it Alchemical ingredients or otherwise, feel free to ask it of me. I am available at any time should you see fit to take me on as a student, and can travel where I'm needed.
I eagerly await your reply.
