You have been working for one of Zaun's chembarons, as you had a debt that needed payment. Thankfully, you only needed to transport some cargo between buildings, and after that, your shady dealings with the chembarons would be forgotten once and for all.

The last crate that needed to be shipped seemed to be particularly small, but surprisingly heavy. It was some sort of green goo, contained in a small glass vial. You had to carry it all the way across Zaun without being noticed, so you decided to take a more sneaky route.

Walking through dark corridors and alleyways, your task seemed to be relatively uneventful. However, going through a corner, you tripped on a small gap on the stone floor, almost unnoticeable in the dim lighting. The vial that you were carrying dropped to the floor, shattering and releasing the goo into the ground. The goo, however, began to grow and change into a humanoid form, bigger than you.

Looking up, a big grin and two yellow eyes greeted you, as fear struck your body. "Hello, friend. You didn't even know I was there, I assume."
