Coventina's outfit draws a lot of attention, and that attention runs the full spectrum. This dude walks straight into a wall. This gawping teen walks straight into this older dude who's glowering in disapproval. This random girl with a staff winks and tosses Coventina a coin. This dude stops in his tracks and starts walking backwards instead so he can appreciate the view. This dude doesn't stop as he stares and trips into a decorative shrub.
The adventurer's guild sits at the end of a cul-de-sac, large and imposing, white brick and red roof tiles.
Inside, it is full of rowdy men and woman enjoying meals or bragging about their quests. An open floorplan filled with bench-and-table seating, under an exposed-rafters ceiling from which various adventuring trophies hang. There is a bar with drinks, another bar with food, and a long, much fancier counter stretching across the back wall that wouldn't look out of place in a 20th-century bank.
They get some interested looks as they walk in, but Coventina in particular gets less extreme reactions than she got outside, given that maybe two-thirds of the female adventurers are in bikini armor or something even more revealing, and at least half of the male adventurers are likewise in barbarian loincloths or other similarly minimal amounts of coverage. She still gets plenty of appreciative leers but a few of those looks are a little more impressed and curious than lustful.
