Avan heads back to the group and reports, "There's a false wall right there. I suggest quietly trying to take a look. Then we can leave, especially if something goes wrong. Perhaps just the quietest of us - Rivoril and me?"
Avan slowly and quietly looks for a lock or traps on the door and stands aside to let Rivoril do the same. When safe, he tries to open it just a fraction to peek inside.
Out of Character: Taking 20 on Search for a total of 30, but it's capped at 20 because of no trapfinding ability.
Rivoril, focusing more now on the false wall, with Avan. While moving silently, has a closer inspection of it. Looking for any locks, or traps, unusual devices, leavers.
Out of Character: Before searching, Avan would cast Lesser Vigor on himself and his jackal to heal as they search. Also, Avan's Move Silently bonus should not be so high due to not having his Boots of Elvenkind and his armor check penalty. So I rolled a total of 6, not 15, geez those make a huge difference together.
Avan whispers to Rivoril, "Can you still send a Message to the others?"
Out of Character: Is the fake wall on the gate thick enough to block their arrows if we hide behind it? Do I think we can close the gate fast enough for them not to reach us?
The fake wall is thick enough to stop arrows but you will have a lot of space to cross over to get to where the exit is at. They can move to where you are but it will take one action round. If you wish to run you should do it.
Rivoril, whispers back at Avan. "Your right, I need to inform the others quickly, of these hostiles."
"You, will need to provide cover for me, as I temporarily face the other direction," he adds.
Rivoril, looking back, facing from where both he and Avan came from. Points, in that direction. Invokes his message. Sending the following message, to the others.
"We have encountered a false wall, which masked a very large gate, which we opened. Behind it is an equally large tunnel heading deeper underground.
"Unfortunately, for Avan and I, we are both seen by a large group of Ogres. Armed with bows and large swords."
"They, have asked us to drop our weapons, and come with them peacefully. Or they, take us by force."
However, there is a hallway about 15 feet wide, behind real wall."
"Myself, and Avan can either make a run for it, down hallway. Or run back to your position. Or we can wait for you to reinforce our position,"?
Out of Character: So that, the Ogres cannot read his lips, and also to aid effectiveness of spell. Rivoril, faces the opposite dirrection to which the Ogres are looking. Rivoril, takes up his action in doing this.
