Keller dismounts and looks for a relatively covered path to get closer to the wall.

BB sticks near Storm, knowing that is where the action will be, hops down from his horse when they get to the rubble.

"They did a number on this place!"

("Attempting to ride them over would risk one of them turning an ankle, or worse." What is your ruling for Black regarding this^^)

((Black would have an easier time getting over without you on his back, but he's more nimble and scrambley than the horses, so wouldn't have an issue joining you within.))

Grandpa will step of Black, and will walk onto the rubble, at the back of the group, with black next to him. Red will fly about 15ft above their heads.

Riding his mount as close as he dared, Storm vaults from the saddle, already scanning what he could see through the broken-down gates. He nods to BB as the other comments on the state of the place. Without responding though he clambers up the rubble and to the gates, trusting his squads to follow as their leaders desire.

With his cloak flapping in a slight breeze, Storm looks into the battered city, looking for the threat he knows to be close. He moves a hand up to the hilt of the sword sheathed across his back, gray eyes intent. An aura of menace seems to come off of him as he prepares to fight.

Do the un-rubbled walls seem scalable to someone like Keller?

Storm and BB clamber up the rubble, no giants are currently visible, but the effects of their destruction is, buildings with roofs staved in, some looking like they were sat upon, rubble littering the streets. Blood has been spilled in the streets, including the mound they are currently standing on.

"Pssst. Are you... are you here to save us? Please..." a wretched sob comes softly from above, from under the vegetation piled atop the guard tower. A dirt and blood streaked face looks down from the crenellations. A man, the grime on his face lined with the wrinkles of age.

((The walls are 20 ft or so tall, the towers are closer to 30 ft. The walls were in moderately good repair prior to this, so they are as scalable as a 20 ft wall would be to Keller or anyone else. Do you have something in particular he would attempt? It'd be an Athletics check to try, you'd need to make two successes to make it to the top. You can let me know what he'd want to know or try, and I can let you know if some other roll is needed?))

Glancing up at the man above, Storm lifts a hand in greeting. "We are here to see what is going on." He informs the grizzled old man with a nod. "Do you have any forces that can aid us in dealing with these giants?" He asks with a glance around to see if he can spot any others. "How many giants remain in this place, and where are they located." He does not remove his other hand from the hilt of his blade as he speaks to the old man, and gestures BB to keep an eye out around them, so nothing takes him unaware as he talks to the man.

Keller will move to the entrance and skip trying to climb the walls. Moving quietly and out of sight.

Stealth: 21

The old fellow gives a sobbing laugh devoid of humor. "Forces? We're prisoners... trapped here until they get hungry or bored. If there's anyone still free in the city, they are staying hidden. About a dozen giants? It's hard to tell, they all kind of look and smell similar. Leader is the big one with armor on him."

"Where?" Storm asks as he looks around the city. "Towards the center I expect, but do you have an exact location?" He glances back to the old man, then out to his squads. He makes sure they are ready, so they can move out once the old man tells him a direction.

BB gives a lazy salute and keeps his eyes and ears open for trouble.

Perception:22

Bryn dismounts, draws his rapier and moves to the wall closest to the entrance and waits for the word to enter the city. As a former bounty hunter sneaking through city streets while on an investigation is his thing, though typically not while the city is being ransacked by giants. 

Grandpa moved forward standing right behind BB and Storm, wand in hand, Red above him and Black at his side.

Bolt had readied her amulet to become large and fight those giants. But seeing these victims of their senseless destruction, she releases the magic and quickly grows to a large size. 

"Don't be scared, I am coming up to check on you!" With this, she nimbly climbs up the wall to check on the refugees and also get a good vantage point to look out over the city.

((perception check once on top to see where the danger is lurking in this city)) 11

Bryn and Grandpa move into position, while Bolt embiggens herself and easily leaps up and catches hold of the battlement, peering over before hauling herself up. It's a bit narrow for her size, but she perches there easily. The ruined city is a bit smoky in the approaching dusk, and she sees large figures in the distance, but none in her immediate vicinity. 

Not getting a response from the old man, Storm looks up to Bolt. "Do you see the giants?" He calls up. "Which direction are they?" Once he has the answer he turns to his squad leaders. "Deploy your squads as you see fit." He nods in the direction of the giants. "I am heading to have a discussion with the unwanted visitors to this city..." His grin leaves no doubt what his sort of discussion will involve.

"Hey, Bolt! What you see up there?"

The old guy must have gotten distracted by the big blue dragonborn clambering up the wall.

"I think they set up in the city hall. Fancies himself a mayor or something. Middle of town, other side of the canal."
