It's a fantasy role-playing game.

DM: You are Fjord, a half-orc warlock . You are the member of the famous group of adventurers. Previously, The Wharfmaster has heard of Marius LePual, a dubious sort of prick, and he's probably hanging out at a waterfront dive somewhere. The other party members go to the Mother's Lighthouse, where Gladys, the Lightkeeper, is a follower of Melora and admits them because Caduceus is, too.
DM: You guys eventually gather in the center of the Open Quay. This is the western side of the docks on the city. Whereas the Restless Wharf seems to be a really busy dockyard that runs a very tight ship, and seems to be filled with elements of cheap entertainment and in that vein, the Open Quay, it's a little a little bit smaller. It seems to be less organized. But in the center of it is this one massive tower that looms over the entire district of this side of the docks. It's an emerald stone-- dark green with elements of light green flecked through it-- spire that seems very out of place amongst the rest of the storage buildings, and the various other small homesteads and businesses that fill this entire area. It seems to be dotted with a number of small balconies, and comes to a slight roofed peak that is like a sharpened point. It's very out of place here. You've passed by it a couple times before, but you haven't really inquired much about it, as most of your business here had been on the job, so you've not really cared to ask or question.
Player: I was going to say, as we're walking, can we snag a passerby and ask what that structure is?
DM: Sure, you grab an older fisherman, thinning hair, very sun-weathered face, is carrying a small sack over his shoulder, various supplies and coiled rope over the other shoulder as he's heading off towards the docks. Stops and turns. "Can I help you?"
Player: (raspy voice) Yes, we're new in town and couldn't help but notice that structure there. Very unique. What is it?
DM: "That's Tide Peak. That's the tower of Yussa Errennis, the mage who owns this district."
Player: There's a mage that owns this district?
DM: "Yes. To the chagrin of the Clovis Concord, yes."
