Update: Day Fourteen

The Investigator, curious as to where The Hounds went, goes to investigate the other locations identified on the map Rustin discovered.
This lead to several abandoned buildings but one of which stood out, The All Saints Church.
The key granted access into the old church and The Investigator discovered signs that other Hounds were housed but were also taken away.
One remaining hound was literally halfway through the transformation when the process seems to have been halted. He was given the nickname Half-Baked because half of his body and half of his face were still human.
Within the debris around Kennel area of the church, The Investigator discovers a curious ring and drags Half-Baked back below the city for later investigations.

Update: Day Thirteen

After verifying and replicating the key and then returning it to the apartment, The Investigator returns to the Knoll and climbs down into The Pit
The Investigator discovers that three of The Hounds have been removed, leaving only the one more recently converted, nicknamed Levis behind. His nickname stuck because though he had been converted, he was still wearing the ripped remains of his jeans.

The Investigator pops over to the Guardian to compare "campaign notes" with Rustin and then later heads over to the apartment of The Bland Man.
The Bland Man and The Jumper are discovered having a quiet, almost cozy evening at home. When the woman's father calls to locate his daughter, The Jumper perfectly imitates her voice to say that she's going on a three month trip to Italy as part of her job. It's a great promotion and learning experience.
The Investigator has to wait until the couple goes into the bedroom for the night before any real investigation can begin. Eventually a key fob is found in the satchel of one of the two men - a possible way of opening the access panel.

The Investigator heads back down and tries the plan again. This time it works better - though not completely but is interrupted when the panel is opened and someone is dropped down from above.
The sound of the person, bound and gagged, hitting the floor some 15 feet below draws the attention of The Hounds and a fight ensues to keep them from ripping it to shreds.
The Investigator recognizes the figure as the woman from The Bland Man's apartment - the one that forced The Jumper to leave so abruptly.
Unable to fight off four of The Hounds alone, or leave the figure there to be shredded The Investigator tried to climb out with the hounds attacking.
With a bit of assistance from Rustin, The Investigator is able to climb up with the body of the woman while The Hounds are distracted.
She's been beaten and tortured to the point of death and won't survive waiting for an ambulance who, with the police, will ask more questions than The Investigator is willing to answer. So the woman is taken away by The Investigator and allowed to pass peacefully, the body hidden below the city.

The Investigator returned to The Pit with a plan to pacify the guard dogs so that the prisoner might be freed. But by the time they could crawl down into the tunnels, the prisoner was no longer chained to the wall and a fourth Hound had joined the pack.
The plan to pacify them didn't exactly work out so The Investigator would have to try something else once they calmed down.

The Investigator returns to the park to explore the tunnels below the access panel but it's locked and doesn't want to reveal to others that it's been discovered. So they try and find a way in through the city's sewer and tunnel system.
They eventually find a sewer junction of two large drain pipes that create a vaguely 'plus-shaped' space with a ladder leading up to the panel above. In the end is a metal sculpture of a large bird and an altar, to the left they see a man chained to the wall and to the right debris has been piled to create a narrow opening to a smaller niche area.
The slightest sound attracts the attention of three mutant creatures that spring out of the side niche and search the room for any sign of movement. The chained man can only moan in pain and appears to have been beaten severely and chained to the wall. A sacrifice for later?
Later, at the gaming shop, The Investigator demands answers from Rustin and the two have a very delicate conversation. It's uncertain as to where the game master's loyalties and interest lies but answers were needed.
The Dogs are roughly humanoid with multiple eye spots, a fanged jaw and a forked tongue as well as long talons on the tips of each finger. Not wanting to get into a fight just yet, The Investigator heads back to Guardian Games to get some answers.

It takes some doing but eventually the identity of the bland guy is discovered and The Investigator goes to investigate.
The address found was a small apartment complex near campus and the bland guy had a place on the second floor. The Investigator saw more than they expected through the balcony door but what really sparked their curiosity was when they saw another man leave the apartment by leaping down without any observable effort.
So The Investigator followed this new figure, called The Jumper, to where he was going when he left. He drove to a poor section of town, to a cramped and tall apartment building and walked around to the back of the place before jumping up to the second floor balcony just as easily as one might hop a few steps in a single leap.
The Investigator followed him inside and waited for him to go to sleep. A possibly innocent tattoo was seen on his back, between his shoulder blades of a black bird. Worth noting.

Curious people be curious and sometimes ya gotta wonder if games are just games or if they're hiding something under the surface. The center of the maps all scattered on the counter looked like it was at a central park in the city. So, what's The Investigator to do one night but to go and check it out.
An access panel is found on a small knoll in the park, like the hatch that might lead to utility tunnels below. Locked and too sturdy to just force open, the panel has a curiously occult symbol emblazoned on the front - like pagan graffiti. There's crossed bird legs, a mystical eye, drops of blood - it's almost comically complex and easily dismissed...until...
With the half-moon hanging high in the night's sky, a suspiciously bland looking guy in dark clothes is seen walking up to the knoll and approaching the panel. He bends down, fiddles with the panel for a second and then opens to climb down into the tunnel below.
Hours later, he finally emerges, locks the panel behind him and leaves the park but not before the Curios get a good look at his license plate.

A typical night at Guardian Games and Rustin is curiously examining a collection of maps laid out across the counter. The maps are all of the city of Prospect with several, seemingly random locations circled with notes scribbled off to the side. To the observant eye, the locations form a curiously symmetrical pattern with a single point at the center with a large question mark drawn in red around it - the gamer doesn't seem to know what might be located there.
Is it a prop for a game - one of those Black Dog things where the worlds of modern and mystical merge into a new and creative genre for modern horror gaming? Who's to say? Well, one person, who we will call "The Investigator"
