It's not really a "horror story", but it pissed me the fuck off to no end. Playing D&D with my friends. We've got a good party dynamic going on: Warlord based off Judge Dredd, a racist Dwarf who's family prophecy is to stand on the highest land, but is afraid of heights, a Dragonborn Warden who is a big tree hugger, but also pretty suave when dealing with NPCs, and me, the half-elf Ranger who is possibly the only living part-elf left in the world since elves died off 3000 years ago.
We work together amazingly. The Dwarf hates half-races (loves calling them "whore-sons"), but doesn't know I'm part elf. The conversations he and the Dragonborn get into are priceless.
But then, the DM's girlfriend wants to come into the game. Ok, sure, we just lost our on-and-off Rogue and Wizard, so one more is nice. She's a Halfling druid. Cool. She even has drawings of her character and her beast form, which is some weird original-character-do-not-steal!-looking half-cat half-bird thing. Don't ask. Whatever.
Anyway, we need to hook her into the group. We happened to be headed for a temple set into a mountain, and as we're coming near it, the DM has me roll a percep, and I find some strange tracks. I make a nature check, can't tell what they are. I decide to investigate. Follow 'em to a dead end, which is basically a rocky alleyway, surrounded by shear cliffs about 30 feet tall. Couple rocks fall from a ledge above me, and my Ranger's instinct it to whip out his bow and point at where they came from.
I see her half-bird, half-cat thing, but no amount of nature check will help me identify it. So, I keep my bow pointed, because fuck, this is a random monster I've never seen before.
Silence in the room.
I make it known again that I have a bow nocked, with the arrow pulled back, ready to shoot at this unknown animal. I'm a hunter, after all.
