You hold out the book, you press it to the symbol on the door, and! Nothing happens.

“Cool,” Darnic is going to try to open the door and, failing that, will use a crowbar if necessary.

Archy shrugs, then moves back out of the way, and behind cover where he gets one of those Dancing lights to read by. He skims through the pages looking for any description or drawing of the facility. He looks through for a clue to the door's operation, or staff to expect inside.

Darnic tries to pull/push/shove the door open to no avail. After a moment, he attempts to use a crowbar, but even after giving it his all - something about how the front door is shut seems unnatural to him. He can tell the door is made of adamantium, and it seems like it might be quite thick too. 

Archy walks around the building but finds no way in any other way on the sides of the building. He thumbs through the journal, but it seems that their client hid the content of the journal yet again, except for a passage around the middle. It shows an outline of this very building. Archy has a hard time reading a majority of what's on the page, not due to a lack of intellect, but rather it almost seems like its written in broken common and much of the lettering is weird. Instead, he notices where the door is on the outline circled in a fresher ink with a scrawled note in plain common - arcane lock.

Any can roll arcana to see if they know exactly what said spell does, but it wouldn't be hard for any of you to take an educated guess.

Darnic thinks for a moment, “Alright, I’ve got the answer here. I’ve worked with plenty of arcane locks before, there’s always a password and a way to reset the password.” Darnic knocks on the door, “I forgot my password.” Magic writing inscribes along the frame “Would you like to reset your password?” Darnic taps ‘Yes.’ “We just need to ask a few questions to confirm your identity. What is your favorite book?” Darnic squints, “Well, let’s try a best seller, Ru’s Guide to Eberron.” The runes flash, “Correct. Heads or Tails?” Darnic looks puzzled, “Side?” The runes flash, “Incorrect. You have two tries left. What is your mother’s maiden name?” Darnic perks up, “Oh! Yshgar! Oh wait, hold on.” Archy tries to inject with “Cannith,” but it’s too late. “Incorrect. One try left. What is your favorite pet?” Darnic sighs and rubs his temples, “Dunno, Brobot?” The door dings, “Thank you. You may reset the password now.” The group looks firmly shocked and Darnic chimes in, “Password.” “Password accepted.” The doors click.

"What... What was that?" Yrwin looks very confused.

Darnic shrugs toward the Halfling, “I have literally no idea.”

 "Well that was unexpected." Archy say staying behind some rubble for cover. "Go ahead and kick it open." 

Darnic will open it!

Inside you see the dust caked walls and dirty floors of a building long abandoned. It's clear that no one has been through here in quite some time.

The foundry seems to be made-up of just a large, singular room. A workshop for only a handful of artificers for sure.

A large chunk of the ceiling has fallen in, crushing cabinets shelves beneath the weight of brick and stone. The remains of what appears to be a quadrapedal metal creature is evidenced beneath the rubble.

You see two pairs of eyes glow from the darkness ahead of you. Two metal dogs creep slowly toward you. Their focus shifts from Darnic, Willie, and Yrwin, seizing them up and growling. Then, they leap towards you!

Battle has begun!

Darnic with grimace with pain as his blade flares with lightning once more. He’ll charge forward and intercept one of the hounds as he tries to jam his blade into their inner workings! Booming Blade: Attack: 10 Damage: 12 slashing damage + 3 magic lightning damage AND 7 thunder damage if the hound moves!

Archy leans around the corner and let's a bolt fly, taking Darnic's target, and hitting AC 14 for 9 piercing damage. Then he darts across to the other side of the doorway to cover with a Surge of Action, firing another shot to hit AC 17 for 8 piercing. Then he draws his second crossbow, to prepare for another volley.

When he spots the mechanical dogs Yrwin releases a yelp of his own. He flings a pinch of cayenne at the one that Darnic is attacking. 

Fire Bolt: Attack: 8 Damage: 3

Willie attempts to cover the dogs in faerie fire

Unfortunately for everyone, your attacks find no purchase save for Archy's follow-up bolt. The metal chassis of these beasts prove sturdy as your attacks gleam right off! 

Willie, however, decides to shed some light on the situation...! While one of the metal pups manages to dodge out of the faerie fire, the other flows with whatever color Willie chooses.

The unlit dog, which has yet to be attacked, shows off rows of sharp teeth as it attempts to bite the half-orc! The othet metal dog, glowing, jumps at Darnic and follows up its partner's attack with its own.

All attacks on Darnic:

Lit Dog: Attack: 8 Damage: 9

Unlit Dog: Attack: 19 Damage: 7

Darnic manages to parry the clearly lit dog, yet, in his distraction, the other hound clamps down on his bandaged arm! Screaming out in pain, Darnic falls to a knee as his arm is wrenched back by the metal beast. Breathing heavily, Darnic can feel his vision blur, if only for a moment. Blood drains down from the wound to the base of his hand. Roaring in pain, red light pulses from underneath his bandages as a bolt of crimson energy releases Darnic's palm! CHROMATIC ORB! Attack: 13 Damage: 9 lightning damage toward the unlit one!

The energy crashes through his palm and blows every servo in the mechanical dog's body with ease. It falls over fried.

Lit dog is still up. You all have advantage against it.

Archy tries to capitalizes on his advantage, he runs into the doorway and fires both Crossbows at once at the remaining foe, hitting 25 for 8 and 22 for 2 piercing. He holds the spent crossbows out to the sides and let's them fall to the ground as he pulls his Shortbow from his back.

Archy manages to leave a huge dent in the dog, but it's still up and barking!
