The Orichalcum And The Spirit

The wind blew hard and rumbling was audible from the distance, but the megaphone easily overpowered them all. "Throw away your weapon and come out slowly. If you surrender properly, you may survive. You resist, we'll drag you out kicking and screaming. Decide fast, we're not letting you waste time in an idle hope there will be some cavalry!"
From behind a large rock came a mocking response. "Hah, you really don't realise who I am, do you? What, did you think I was just a little lamb? Congrats, you're the lambs led to the slaughter now."
"Stop taunting us and come out now. We know you cannot defeat us. And there's no backup nearby."
"Oh please. So occupied with your prey that you don't properly observe your surroundings. Have you not noticed? The thunder's coming closer and closer, yet there's not a single cloud in the sky. So pray tell, where do you think that rumbling's coming from?"
"You're bluffing. Last wa-"
They finally saw it, the figure gliding towards them. As it approached, it let go of the glider and fell down, crashing inbetween them and their target. The dust quickly settled, but what it unleashed was a large figure still not properly visible, as lightning sparked around the troll. As their minds raced, forming new battleplans, the voice once more rang out from behind cover.
"Welcome to the chopping block. Target, you. Price, one single dram of Orichalcum. Congratulations, gentlebeings, say hi to your butcher."
