The red squares (sawblades) and the orange squares (gears and machinery) are not walls, they can be moved through, but doing so is dangerous.
Dex save (DC15) or 2d8 slashing damage if you enter, or start your turn on, a red square.
Dex save (DC15) or 2d8 bludgeoning damage if you enter, or start your turn on, an orange square.
The catwalk is 10' up, and hugs the wall. (characters on the catwalk can be anywhere along the perimeter of the room, in other words, and there are no saws or gears along the catwalk)
New For This Round
Logs. One may jump to, and move along, the logs in the pond.  All logs are 10' long.  They do not count as difficult terrain, but landing on a log will prompt a DEX (acrobatics) ability check [DC10] or the character will land prone.
Ladders. The ladder the guard is on is 20' tall.  He is currently climbing and is at 10' elevation.
Combat While Climbing. Climbing requires the use of at least one hand (no two-handed weapons).  Attacks made vs a climbing target will be made at Advantage. If hit by an attack while climbing, a STR (athletics roll) [DC10] will also be required or fall.

Cassian grimaces slightly but makes his best attempt to stay standing as he jumps for the nearest log. He barely manages it.

Acrobatics: 11

Absolutely sure that luna is death doc follows behind cassian standing outside he asks the gods to punish th guards. Casting 2nd lvl guiding bolt:

To hit 13 for 19 dmg but using a channel divinity for guiding strike giving a +10 for a 23 to hit. 

Quote from EmileTherese >>

Acrobatics: 11

 That movement finishes up last round’s actions.  Feel free to post a full round’s worth of actions for this round as well. 

From the log he is on, Cass will attempt to jump two logs to the west.

Acrobatics: 18, 18

He will attempt a javelin throw at the climbing guard if possible.

Action: Javelin to hit with advantage 23, damage 7 and slow

Navrine runs to the edge of the cliff and uses her sling at the guard on the ladder.  Then she crouches by the edge of the cliff seeking partial cover from the deadly crossbow of the guard.

Movement: 40’ (up to the edge of the cliff.)
Action: Sling attack.(15)+5 for 20 to hit  (4)+3 for 7 points of damage.)
Bonus action: step of the wind (move 5 or 6 feet back from the edge seeking partial cover from the top of the cliff.)

The fleeing guard scrambled down the ladder, his breath ragged, eyes wild with desperation. Navrine was close behind, feet barely touching the rungs as she descended with the speed and grace of a striking hawk. Below, Cassian and Chromir made daring leaps from the edge of the pond to land upon the floating logs between them and their quarry. The paladin’s armor clattered with each landing, while Chromir’s boots splashed cold water on his legs as they bounded across the rolling timber.

But it was Doc who brought the chase to an end.

Standing at the edge of the sawmill, blood still seeping from his wounds, the dwarf planted his feet and raised his warhammer high. He called not with fury, but with bold authority — a prayer uttered through bloodied lips, rising to an accusatory shout.  Overhead, a storm gathered, sudden and brief, as a lance of divine light split the early dawn and struck the retreating guard! The man seized, screamed, and tumbled from the ladder to the earth below. He did not rise again.

Silence followed. A silence not of uncertainty, but of finality.

The light of the coming dawn began to peek through the trees. 

The last of the baron’s loyal men had fallen.

With the guard down Doc goes to his knee, to catch his breath, to remember how close he came to death. 

He does a prayer and thanks the lord of the twin axes that his friends kept him alive.

Navrine reaches down and makes sure the guard is dead. Standing there numbly fists slowly flexing. So much needless violence. She says a silent prayer to her god. Then turns to her companions, “I guess I should lay the dead to rest.” She picks up the dead guard “Then we can check on Darin”

Cassian's shoulders slump in relief as the guard falls, though he can't afford to relax too much from his precarious place on the logs. He gives Navrine a wave of acknowledgement before carefully making his way back into the mill. It's hard to resist hugging Doc, but the paladin manages to limit it to a pat on the shoulder seeing as the dwarf is still hurt.

"W-we did it," he says with a small smile, moving to collect his sword just in case.

As the adrenaline ebbed from the heroes’ limbs, the first rays of sunlight continued to creep over the rooftops of Hope’s End. The sawmill, once filled with screams and the sound of battle, now stood still — blood soaking into the sawdust on the floor, the its massive gears groaning quietly with every slow rotation.

From the edge of the woods and the winding path to town, villagers began to appear in twos and threes.  Some clutched lanterns. Their expressions were wary as they approached ... and then, slowly, hopeful.

A carriage of lacquered black wood and polished brass wheels rolled into view, framed by the rising sun.  Imperial crests marked its sides, and a liveried driver slowed the horses to a respectful pace. Flanking it were two riders bearing scrolls and ledgers, their uniforms crisp despite the morning chill.

The magistrate — summoned by Baron Thorne as part of his plot to frame Darin — had arrived.

Doc, Finished with his prayers, looks as the carriage arrives. Wondering what the magistrate is doing here.

Cassian finishes catching his breath as he notices the carriage arrive. So Baron Thorne had really sent for a magistrate after all. "It's a s-shame the Baron didn't make it. He s-should've had to confess to everyone and face justice properly. I...h-hope the magistrate will believe us about what happened." The paladin tries to steel himself, spraying on a bit of perfume before heading out to meet the passenger in the carriage with a solemn expression.

The carriage came to a halt before the battered sawmill. Its door opened with a soft clack, and a woman in a dark coat stepped down, the silver trim of her uniform catching the new morning light. Her hair was tightly bound, her expression measured and sharp. This was Magistrate Elowen Vance, an agent of imperial law, and as her boots touched the blood-streaked ground, all chatter among the villagers fell silent.

She surveyed the scene — the wounded heroes, the fallen guards, the wreckage of battle — with a cold, discerning eye. For a long moment, she said nothing. Then, with a short nod to her attendants, she stepped forward.

"You have done what many would not."  She said, her voice clear and carrying over the milling crowd.  "You brought justice to a house that had long since abandoned it. Baron Thorne’s crimes, once cloaked by privilege and fear, are laid bare for all to see."

Her gaze swept across the heroes.  Doc, bruised but standing proud; Chromir, still breathing heavily from battle; Navrine, her fists bloodied but steady; Cassian, their sword lowered but ready.

"For this, you will have the thanks of Hope’s End — and of the Empire.  You have torn down a tyrant and returned this village to its people."

At her signal, one of her attendants produced a satchel of official seals and documents. Others from the crowd set to work. The baron’s coat of arms was being pried from the sawmill's entrance, stripped from the doors and windows of nearby buildings.

"There will be no more lords here."  Magistrate Vance continued, her voice rising so that all could hear.  "Hope’s End will govern itself until a proper reeve can be elected. No more stolen justice. No more vanished daughters."

A murmur of relief passed through the villagers. Some wept openly. Others approached the heroes with tentative smiles, small offerings of thanks — a loaf of bread, a patchwork cloak, a quiet hand on a shoulder.

The long night had ended.

And so, under the watchful eyes of those they had saved, the heroes of Hope’s End stood together, weary but unbowed, as a new day began ...

Chromir was more than happy to help pry any of the Baron's sigils from anyone in town. "The baron had his strange flower. I don't know if that is related but I can send words to my druid friends and see if someone can come identify it. We should know what it is before we risk spreading its spores." (and he will try send word any way possible, but I am not sure how far away the druids from his backstory are to Hope's End)

Doc looks on, at this strange sight. Wondering why the Baron was left as a lord when it was apparently known what he was, but is smart enough to not ask questions. Being happy they do not have to explain themselves to what happened.

He does know he quiet like this place and has decided to stay here for the time being, helping this village to rise for what it will be.
