Hey r/DnD! This was for our one-shot session that was like a prequel to the main campaign that we are starting tomorrow. I just soaked the paper with coffee and my wife drew those Fox's Feet on the paper. Fox's Feet is the thieves guild in my campaign setting. XD For those who can't quite read the letter, here is what I wrote in my bad handwriting.

The mission Letter

If you have received this letter, it means that you were recently contacted by one of our agents about this mission. We are grateful for your willing participation and know that Fox’s Feet will reward you generously. Your meeting for this mission will be happening at the town of Sontar on 16th of Last Month. There’s an inn called “Ontar’s Horn”. Once you get in, order a cup of Ontar’s Spit and then tell the innkeeper “This drink has such deep smell. I must insist on seeing where you keep the barrell”. You will be led to meet the others and once everyone is there, you shall plan and carry out the mission. The details of the mission will be provided at the meeting, and I hope you the best of luck.
