Duking it out with the Shadow Duke

Another odd chunk of time, after getting back out of that pit Llobh summoned some screeching small dragon like creature from some concerning dimension before dismissing it realizing it was not as stealthy as we were hoping to be. Ezekial heard some sort of skittering and then some giant worm thing popped down paralyzing many of the others. Polis and eye were able to dispatch the creature after he scared it off allowing us to find a new spot to position more safely.
Once everyone else became able to move again we continued exploring and finding more and more icy floors and chilly areas - a frozen fountain was found with water still running that Khaggy found had a lever leading to a secret tunnel back to the old cistern. There was some busted altar that I snagged a chunk of not sure if that will ever proof useful but if not it's an interesting story for a rock at least. Some old illusion faltered, as happens with such useless schools, on a statue of some lady with a dead man nearby.
A soft humming sound was occurring immediately returning thoughts of the smell of burning and the sound of thunder nearer the clock lock but it turned out to be 4 orbs being manipulated by some "Shadow Duke", pretty lame name as expected from an apparent necromancer and insane follower of the Frostmaiden. Khaggy charged the duke himself while we dispatched some skeletons and targeted the orbs.
Likely the oddest part here was the return of the floating guy from the inn who is apparently called Calarel giving some odd red coins to Polis for the work done in this mine(?).
