Hello? Lord Baelish? This is Princess Allura. I believe we talked briefly over the Network a few weeks ago.

I may be visiting Maurtia Falls in a few days, in an attempt to know this world better, and I...was wondering if you'd be available to follow through on your offer as an escort.

I would understand if you are busy.
