The Valley of Ends

"So we need to find a bridge. We are a bit exposed here in the riverbed. Lets go up and then move upriver." 

Lyrant follows Onyx.

The party moves without a rest upriver. As the partt moves across the riverbed, corpses of various monsters, beasts and humans can be found, all in kinds of conditions. some looks like they were ripped apart, some bitten to death, some burned but most unerving part was silence. All these corpses and no sounds beside the rushing river. 

The party finds a rope bridge set across the riverbeds over the river, three rops tied to posts on either of the riverbed in a V shape. (Requires acrobatics checks from group to cross it)

Oh this is going to suck.

Lyrant acrobatics: 18

It wouldn’t even work with Guidance, since the most I could get is a 4.

"That looks like a good place for an ambush to me. But i also feel like we are under time pressure here. I would suggest i cross first and secure the other side, and then you follow. Do you have any spells to secure me while going over there?"

I would cast [spell] zephyr strike[/slepp] on myself before crossing, store my weapons and have my daggers at easy reach. 

Can we see any movement?

Lyrant will cast Guidance on Onyx.

How wide is the river here?  How long is the bridge?

The river's width has changes much as you move upstream, still lingering around 200ft mark with the rope bridge about 250ft long and about 30ft above the river.

Onyx search the area for any signs of the monsters he was told about but only seem more corpses, some even piled up like a battlefield. Just on edge of his sight, he could make out something going across the river but it's hard to tell from this distance.

Noticing Lyrant and her trouble to cross the rope bridge Raynor will begin to lightly tap on his drum to build a beat and sing to her
"Luck ain't enough
You've got to make your own breaks

Once everyone is set Onyx will sprint across the bridge, useing his feline agility to rush the first leg (120 feet) and then move(dash) at normal speed.

If he gets to the other side without trouble he will take out his bow crouch down and keep an eye open for danger. 

The party collectively manages to cross the rope despite it twits and leans. Onyx managing to catch Lyrant as she slips for a moment.

Looking around you just see a flatten city with a clear view of a pillar of pale white light. Just piles of debris, corpses and sort susans between you and the polar in the distance. It'll take better party of an hour to get to but it's mostly a straight shot to it.

Lyrant thanks her companions for the help.

Onyx looms at the destruction in front if them: "Onyx thinks most of the sewer will be caved in from here on. Onyx thinks we got a better chamce to stay overground. We should keep in mind, that we need to get out of the city and back up the mountain as well." 

Gotch waves a cloth into being and dabs at the sweat on his face.  "Let's get this over with, just remember we aren't the only ones after this thing..."

Lyrant nods in agreement. She stays silent, hoping for a sign from Selûne.

The party continue forward without a break, you climb over, walk around and shove corpses that litter the grounds. The party finds bandits and other humanoids on the outer edge which founds become beasts and undead as the party inches even close enough to see what causing the pillar of light. Among the bodies of monstrosities of all manner, a silver cresent hovers in the middle of the pillar of light while a milk white liquid seems to pour from it, forming a pool underneath that doesn't grow as more liquid pours down. 

The party quietly appoarch, they see a trench of upturned ground has been formed around the relic where what seems like bones sticking out it for a moment but they start to shake and move thtough the soil before a large skeletal serpent emerges fully from the ground, starting the party. 

Situation
The enemy is about 60ft from everyone. It's mostly open terrain but some hiding spots behind corpses and ruins are available.
