As a result of Mullo's attack, Fast Wing is the only griffon left (and there are no berserkers either). 

Devin you're up! Fast wing is surrounded on three sides by Illezenya, Mullo and Haetone, however at a cost of 10 feet of movement you van close to Combat if you wish. 

Devin moves in to finish off the last griffon with attacks from both his staff and spiritual weapon. 

Attack: 23 Damage: 10

Bonus Action Spiritual Weapon

Attack: 24 Damage: 6

Devin's blows drop the final griffon. So now what?

"How do you all fare? Does anyone require immediate healing, or shall we continue looking for the yakfolk in these mountains?" Ilezenya asks. He then notices his own gashes and wounds from the battle, and heals himself a little... (1st level Cure Wounds: 8)

D.O.R.K gives her body a once over. "Significant damage sustained, but not beyond operating parameters." She assured Ilezenya, and by extenson everyone else, before then looking to the bodies. "... Shaman Mullo. What do you recommend we do with the bodies? They will need to be removed, but I do not wish to do so irrevantly if at all possible." She further asserts. Once she had her answer, she'd try to assist with disposal/butchering of the griffon meat, prior to then heading elsewhere on the ship to check up on the rest of the crew.

Devin wipes sweat from his brow as he lets the blue stars from the guardians and the spiritual weapon fade away.  He then goes and checks the bodies of the fallen foes, both human and griffon for what they may have in packs, saddlebags or pockets.

"Toss 'em overboard for all I care.  They attacked with no warning or discourse.  They deserve nothing else." he says.  "As for injuries, I've been worse.  Nothing a short rest couldn't mend."

After checking the bodies Devin walks over to D.  "Hold on friend, this panel seems loose."  He then casts Cure Wounds 3rd lvl for 20 hp to D

He also Harnesses his Divine Power to regain a 2nd lvl slot.

As the last griffon falls, Mullo hurries to Haetone and begins examining her wounds. The two have a short conversation where Mullo fusses over the pegasus while Haetone appears to want no more healing. Mullo doesn't like it, but respects the animal's wishes and turns to scowl at Dork. "Burn them," she says coldly.

While it initially looked as if D.O.R.K might reject Devin's request, her hand soon fell to the wayside to let the cleric perform his treatment. "... Thank you." She said softly. After glance back at Mullo again, she pantomimes sighing with her whole body and shakes her head.

"A crude compromise would be to set them aflame and then throw them overboard... but that shan't be done. Rather, if we can find a flat enough area to set down briefly and see to a small pyre, that will be enough. This will also give those that would prefer not to deal with them at all time to check over the ship, and make sure their rough arrival hadn't damaged anything too much. Agreed?" 

Ilezenya nods his assent, then starts looking for a wooded section with a flat and open area where they could land. Percep: 15

Ebonitus looks around at the carnage and wonders just what it was that had the griffon riders attack without any apparent reason. Where did they come from, he wonders. To this end he inspects the bodies of the riders to see if they have any identifying marks or items that may help to determine their origins.   Investigation: 18

Mullo clearly does not disagree with Dork's suggestion. She begins butchering one of the griffons for meat and hide.

Fair enough to me Devin answers as he continues looking through bags and pockets.

Noting no dissenting opinions, D.O.R.K redoubled her efforts to help move and separate the dead, and with her trusty dagger, make sure any that had yet been lingering on the brink of death were swiftly sent on their way. The closest thing to mercy she could provide before carrying on in her duties. Ultimately, she leaves Ebonitus and Devin to further sort out the dead raiders, citing in passing to especially set aside their weapons, as well Mullo to her work, once done separating and arranging the bodies for later removal.

Soon enough, she'd find herself below to check on the remaining crew and give them head's up(If one of the not-cultist hadn't already come up at some point to find out about the earlier ruckus). But after which, the construct sought solitude below decks until it came time to officially make their pit stop and see to the dead, preferably before the day was out.

Ebonitus walks silently amongst the dead, feeling sadness at the needless loss of life, still wondering what it was that the griffon riders saw that made them attack indiscriminately.

After the party has cleared the remains of the barbarians and the griffons from the deck, during which Devin finds no more than the odd trinket, Mullo spots Ebonitus shaking his head at the destruction caused by the aggression of the Griffon riders. She walks over and says "don't try and understand it, many of barbarians in this region have the view 'what is yours is mine and what is mine is my own' if we surrendered when they first attacked then maybe not as many lives would have been lost but it would certainly put our mission at risk!"

Ebonitus snaps out of his reverie and helps to return some order to the ship as they descend to burn the bodies.

With the dead eventually seen to, and the party once again both on board and on track to the rough coordinates to their destination, D.O.R.K spent at least the next hour still gathering her thoughts and finishing some self-repairs(ie. Short Rest, if able), before finally seeking out the rest of the party members top side.

"We still have a few days before we near our destination. Once we do, we shall attempt an aerial sweep to see if we find any signs of giant occupation, if not lesser settlements, be they yakfolk or not, and speak with any locals on the matter. It is however recommended for those more... attuned to the field to request what divine guidance you can to pinpoint more exact coordinates to Ironslag." She bowed her head as if in thought of something. "... It is best we take then a day to prepare to infiltrate the site. Hostile engagement should be avoided, as we can not expect to be able to negotiate with them outside a position of power... which we sorely lack at the moment."

"Well, I begin to wonder if that blue dragon is the same from the dreams that set this whole escapade off.  It's meddling in some way though we don't know how or why.  Could be just evil dragon hates giants so screw them up sort of meddling.  Time will tell I guess.  Till then we keep our course North East East and keep an eye out for the village."

Devin heads from the prow of the ship to keep watch and see what is ahead.

The airship continues on its journey for the next two days. On the third morning as it moves over the eastern edge of the Cold wood the party can see the mountain range known as the Ice Spires, part of the Spine of the World directly ahead. At the front of the range is the mountain known to the dwarves of the Silver Marches as Mount Hamarhaast, in which they believe lies the dungeon-forge of Ironslag.

Climbing 500 feet from the base of the mountain to a small plateau on which a village has been established is a staircase.

Please let me know where the various party members are on the airship or in the case of Mullo if you're flying on Haetone.

Ebonitus is left side front leaning on the railing, looking at the sights (looking ahead and to the side). He has overcome his fears of being so far from his beloved earth during the time on board the airship.
