“Unusual.” Aazel says simply as he sees the hole. “I wonder if this was used to escape, or to steal a body.” As he looks he tries to figure out if the hole was made from inside the coffin or beneath it.

”I think this is worth reporting back before we explore any further.”

Khazan gets up and goes near Bart.

"Did ya found somethin'? Or did ya felt like cleanin'? Ye've no idea how much dust is under the bed."

Peeling back the carpet, Bart sees the same wooden flooring as the rest of the room. The is rush of colder air as it's disturbed by the quick movement of the rug.

=========

With the light of midday shining through, Aazel sees the hole is well constructed. So much so, you see flat stones keep the shaft walls in place. There are large flat stones dug deep into the walls horizontally to make something like a ladder. The hole goes beyond the dimensions of the coffin.

"I agree that we should probably regroup before we venture down...but that doesn't mean we can't get an idea of this mysterious hole," Daffafle winks at the raven on her shoulder. "Go scouting, Lucky. Stay within one hundred feet, if you don't mind. I'd like to see what you see."

“Hey Khazan... I think these boards said something uncouth about your mother.” Bart pulls out a crowbar from his pack and hands it to Khazan, before going to watch the door.

Lucky caws a little and hops before flapping up and diving into the darkness. He lands on the ground, it's smooth cold stone. There are no lights down here, but through Lucky hears stumbled, small movement and breathless snarls...

Calling Lucky back, Daffafle turns to Aazel. "There are definitely beasts of some sort down there, but what I cannot discern. We should gather the team...should I remain behind to make sure nothing climbs out of this hole in the meantime?"

"It's probably a good idea, but only observe. There is no point getting into trouble just yet. I will be back as quick as I can."

Aazel heads back to the inn to see if any of the others are there to let them know what they had found.

Wulcrath smirks a bit as he watches the rug slide across the floor, before watching Bart reveal a crowbar, wondering how they're going to explain this, his smile fading a bit. Bringing hand to his chin, he looks around the room.

"Ah the cold wind of dissapointment..."

"Jokes aside though, where haven't we looked yet...?"

His foot taps as he thinks, eyes closed in contemplative silence, before he decides to see if he can find anything interesting in or around the bookcase Veylss was sitting by before they entered.

Wulcrath moves to the bookcase, checking the shelves, pulling books from it before returning them, then moving to the area around it.

"At the least I might find an interesting book."

"Sure let the dwarf do all the work ..  "says as he take the crowbar from Bart's hand

"Ye elgi are as useless as an empty mug"

He then tries to pry open the floorboards

Khazan wedges the crowbar into the wood. With a swift and efficient aim, Khazan pins in the bar and heaves, and large wooden door is ripped open with splinters flying everywhere and slams against the foot of the bed.

However, the wood of the shoddy door is of a much darker shade, and the wood-panelling floor still appears to be there undamaged while there's a cool breeze rising from it.

==========

"Are you looking for the other heroes?" The half elf waiter is wiping a table, noticing the half orc. "The dwarf I saw talking to the smithy, unsurprisingly. The other two went for a stroll?" He shrugs before carrying on...

"What in Moradin's beard ..!?! Another wooden floor!? ARE YE KIDDIN' ME!? WHO WOULD HID MORE FLOOR UNDER A HIDDEN DOOR!?! I KNEW UMGI WERE WAZZOCKS BUT THIS!?!"

In a fit of anger he throws Bart's crowbar at the floor (where the door was)

The crowbar just slips on through the wooden-panelling floor without a sound before a clanging sound is heard a couple of seconds later.

“Well... that’s unusual. Let’s hope no one’s down there.” Bart lays down on his chest and feels around through the illusion to see if he can find a ladder or something to climb down on. 

As soon as Bart touches the illusion, it dissipates (for Khazan also) almost completely revealing a relatively well made shaft with wide felt stone keeping everything in place and even. The same type of stones are wedged into the walls horizontally to make a means of getting up or down into the cold darkness.

Bart gives Wulcrath and Khazan a meaningful look, and climbs down without another word. He’ll try to sneak ahead of the others if he can, watchful of traps. It’s bad enough to be unarmed, worse if they all fell into a trap.

Aazel asks for directions to the blacksmith then heads off in that direction looking for the dwarf. 

"Is he daft? Where does he think he's going without a weapon?"

Khazan paces a bit around the hole

"What ya think Wulcrath? Should we go after our intrepid friend or should we go on our marry way an' have a drink at the inn?"

"I dunno about you but..."

Wulcrath sighs as he lifts his pack off his back, kneels down and takes out a torch and hammer, setting the hammer aside before taking out his tinderbox, lighting his Torch.

"I'll see you down there."

He hands Khazan a Torch and his Tinderbox. 

Wulcrath picks up his hammer, attaching it to his belt, before grabbing his bag, slinging it over his shoulder, carefully descending into the darkness, torch in hand.

Khazan looks at the torch given to him and tosses it behind him.
"We're leavin'! I better find me axes when I get back!" yells at whoever might in hearing distance.
Stretches a bit and descendes after the dragonborn, into the hole.
"I'm itchin' fer a good trashin' ..." mumbles to himself on the way down
