Khaffosi will wander over to the altar, not close enough to touch anything, but close enough to get a good look.  

Quote from Kerrec >>

Khaffosi looks at the collpased path and says, "We can come back and investigate here later, if the other directions don't lead anywhere either."

Hunferho will start walking back towards the door down the stairs (option #2 of post 650). (Already done, sorry.)

If Arrow has not already retrieved his dart, Hunferho will (with a look of disgust at the dead rat) pull out the dart and hand it back to Arrow.

Hunferho would also like to Investigate the altar, looking for hidden panels, or symbols to verify that this was for one of the Dead Gods.

Feel free to make an Intelligence (Investigation) check.

Hunferho Investigation: 15

Khaffosi will defer to the more educated folk and just do what he can to assist Hunferho.  Using the help action to give Hunferho advantage.  Rolling 1d20, in case it beats his 11.

9 + 4 (is Hunferho's modifier)

And Khaffosi barely manages to not hamper Hunferho's efforts.

15 Investigation:

Pogo slowly approaches the alter gripping his holy symbol as he does so, "Anything useful my friends?" he asks as he stays a few feet away from this dreadful alter.

Hunferho: "Unlikely that these partly melted candles are hiding anything underneath. I'm going to poke around this box of bones on the back of the altar, with my rapier, to see if there is anything at the bottom."

(Happy new year, folks. Apologies for the late response, I didn't have much time to get to a computer to update posts.)

Hunferho beings to poke around (literally) with the rapier. A series of bones clatter out onto the floor, spilled in the area between the altar and the nearby wall. However, there appears to not be any treasure hidden beneath.

(Bump)

Returning back to the door, it seems simple enough to open and leads through to another dry and partially collapsed room. Within this room is another altar, where several half-melted black candles lie, unlit, towards the right of this small chamber. There is a set of stairs to lead down and to the left out of this room, the bottom appearing to lead into flooded shallows again.

"Blasted cults.  Hope that altar is just superstitious nonsense.  Arrow, are you going to lead us down those stairs?"  Khaffosi gives the altar and the dislodged bones one last look before walking over to the stairway and looking down.

Arrow bounds downs the stairs and eases himself in to the water at the bottom.

Arrow pounces down the stairs and into the shallows of the flooded room. The ceiling is held up by rotting wooden beams, and the room further down is obscured in the dark. It appears to have a handful of wooden beams going from floor to ceiling, with a door to the left, a bend at the end of the room where piles of rubble can just about be seen just before the bend. Between that and Arrow is another turning that leads out towards another corridor.

However, arrow's finely tuned senses recoil as there is a terrible stench, like rotten eggs, that comes from further down the room. (He can make a Wisdom (Survival) check if he wants to work stuff out.)

[Survival: 15]

Arrow:

Arrow scrambles back up the steps and holds up the party and extinguishes the torch(es)

"You do not want to be carrying open flame down there....unless you want to set everything on fire....smells of highly flammable gas..."

Alea looks at the other party members for a moment, especially the fire genasi and wizard before moving to where arrow was “no open flames....got it”

Arrow looks at Khaffosi and considers sending the angry genasi down alone to explode...but decides he's better off with the party.

Khaffosi looks pained, "No open flames?  I can't go down there..."

"Sure you can......once...." and Arrow grins
