A goblin enters, wearing armor, a shield, and a rapier sheathed at his hip. Oddly, he has what appears to be a keg strapped to his back, along with a standard adventurer's backpack.
He puts down his shield, then removes the keg and backpack. Grabbing a mug that was dangling from his belt, he fills it with ale from the keg, drinks it all in one long chug, and then refills it. He turns to look at you, as if noticing that other Pathfinders are present for the first time, raises his mug in your direction, and begins singing.
"Mighty Cayden, god of drunks,
Chose his champion - Me! I’m Grunk!
Wine and ale, I try ‘em all,
Drown myself in alcohol,
No need to read my god’s decree,
Everyone, everywhere must be free!
When evil slavers try their tricks,
I run ‘em through with pointy sticks!"
His song ended, Grunk laughs like a maniac for a few seconds, before taking a smaller drink from his mug. He then turns to look at you with his beady red eyes.
"So... who are you?"
