Erdolliel quickly scouts the nearby area. Unfortunately, it seems that all of the sewer grates are right in the middle of the roadway, with no openings to be found in alleys and such.
After the elf comes back, Nethezar offers critiques as she uses the hair clip to change her appearance to a male worker. Nethezar then uses a spell of his own to change himself to wearing a study, but messy suit of coveralls. "We probably don't need to do too much to Kushnak. I bet the sewers are crawling with rats and other vermin that engineers would rather be handled by some hired thug, right? But we should make you at least less recognizable." The scholar proceeds to dab some make up on the half-orc's face to make some subtle differences.
Nethezar pulls out a scroll with a map on it. "Any close inspection will show that it is not the sewers, but we don't need it to survive a close inspection."
Holding the map in front of him, Nethezar confidently strides to the middle of the street, gently pushing people out of his way. "This one, you lout," he calls back to Kushnak and Erdolliel with a strange accent. "Get this cover off!"
Only barely after Erdolliel and Kushnak can catch up, a guardsman nearby hustles up. "What, uhh..."
"Sewer maintenance," Nethezar turns and explains in the same accent. "Bi-yearly check ups make sure the tunnels don't collapse and all that. Don't need the shoppers suddenly falling into a pile of crap, do we? The bitch of it is the rats and stuff, but Gorsh handles that crap. Hurry up, pull that damn thing off, you stupid oaf!" Nethezar yells at Kushnak. "S'posed to be here yesterday, but damn Sammy here read the blasted map wrong! Spent all afternoon checking the same damn tunnel another crew just checked last week!" Nethezar slaps Erdolliel on the shoulder.
He turns back to the guard. "While you're here, you mind lowering the cover back on after we get down there? We'll be down there at least a couple hours, and we'd have hell to pay if some dumb tourist fell in the hole in the meantime."
In short order, the trio finds themselves in the sewers with a guard lowering the cover back in place over them, while thanking the gods he doesn't have your job.
