Well, I don't think that many people are up around now, but I'm going to go live anyhow and just take really sparse suggestions because we need to make some PROGRESS yo
Go check out the ladder in the room behind the cabinet. If it's still blocked off, fiddle with the dials on the machine.
The ladder remains in place. Looks like you're going to have to deal with the lock itself, not just the power.
You try fiddling with the dials. Most don't do anything, but one turns the weird machine in the doorway to flame. Weird. You turn it off, spooked.
Investigate the computer.
It has three functions and a really old-school interface. Looks like your commands are LOGIN, HELP, or OPERATIONS.
use chimney soot to draw additional facial features on skull, (ala wilson) stow skull safely in inventory, climb chimney!
You leave the generator room and travel back to the smithy, but there is no soot in the chimney. This leaves the weird question of how or why it burned in the first place. You are pretty sure you can shimmy up, though.
You seem to be... outside? You made it! But you're still stuck in some sort of miniature canyon. Light shines down from above; you can't see where you are from here though.
There is a bit pit with some pipes and a drain in it. There seems to be an object jammed in one of them. There are also some circular stones lying on the pit floor. A tree has grown out from the cliff face, and a bird sits happily in its nest. Across the pit there is a mossy wall, a ladder, and a cave entrance.
Turn the powered wall-gizmo in the fireplace room to low, examine any changes.
You flick the dial to LO. You hear the sound of water running through pipes, but no changes are evident, nor does the marker on the display slide.
Can we turn the remainder of the whiskey into a molotov?
Probably! You are not looking forwards to wasting the last of that brew but if a need arises you would accept your duty.
Also, at one point you said there was something inside the chimney but that we couldn't reach it because it was too hot... What happened to that item?
You knocked it out with the hammer. It was the lightning medallion.
Jump into the expanse formerly known as mirror.
You can't fit through the hole!
