Use the Orcish Orphan Whistle to talk with the child you will be looking after during Children's Week.
Assignment:
Orphan Matron Battlewail: You're willing to help us here at the orphanage? Bless you, friend; your aid during Children's Week will be invaluable.
Take this whistle. You will only be able to use it for a short amount of time - typically not longer than Children's Week itself. When you use it, you will be able to talk with the child you've agreed to look after. Using it again will dismiss the child.
By all means Zelhin - use the whistle and meet your ward! I'm sure the child will be most eager to meet you.
Orcish Orphan: Zug zug! My name is Grunth, and I guess you're looking after me? You're an adventurer, like my mom and dad were. My matron says that they died with honor in battle. I'm happy to meet you.
I hope we'll do plenty of things together. I have some things I'd like to do, and the matron says you'll be like a big brother to me during this week. I'd like that a whole bunch.
