[Awatu]

...drops his parcel into a mailbox near the door and promptly leaves, breathing heavily and muttering something about "improper postage". It reads:

I have heard of your exploits across the world and have sought you out with the intent to join your organization in battle.

Awatu has agreed to sponsor me, and I look forward to fighting together.

Rhomga.
