Out of Character: He is in front checking for traps, hearing a noise, etc. He cannot do that if he is in the back but feel free to let Ardo take his place if you wish. .
Out of Character: I can stealth out ahead of the party and report back if that's easier (Although I don't believe I have Darkvision, so that might be a bad idea).
As Davik begins to lead the party down the stairs, checking for traps as he goes, he notices a sudden absence of sound. It's as if the stairwell is completely quiet. Even knocking on the stone reveals no echo, no noise, or even a slight scraping sound.
Out of Character: : Not sure why Davik would need any kind of dark vision as it was previously stated that the room you're entering is well lit.
Hunter stops the rest and asks them to back up the steps to see if there is some kind of magick on them or just in the area. If on them he retreats all the way to the top and waits till it wears off.
Delgar will move back up the stairs. Once at the top I'll examine the steps using my spell craft to see if the area of silence is a magical effect.
Despite the fact that Delgar hasn't observed anybody casting any spells, it's still quite obvious that the silence is magical in nature since there's no known occurrences of pockets of silence that have happened naturally.
"Allow me to scout ahead," said Davik "This silence will give me cover for sneaking ahead, I can see if there are any more traps ahead, and perhaps even what we're up against.
