The tunnel is 20 feet wide at this point, zigzagging irregularly. It is the zigzags that have prevented the sentries from being aware of your approach.

Yix explains telepathically that the two drow sentries have chosen a vantage point that allows them a clear view of about 60 feet of relatively straight passageway. It would be difficult to get close enough to observe them without their being able to see you.

There are rock formations scattered about the passage that make it impossible to charge the drow outpost. Futhermore, the two drow have positioned themselves so that the rocks provide partial cover.

Yix has been able to peek at them around a stalagmite without being detected, but the tiny dragon was unable to determine exactly what unit the drow are from. It seems likely, however, that they are indeed the drow you have been trailing.

Ginevra proposes that she and Yix sneak by the sentries to locate the main group of drow and grimlocks. Once this has been accomplished, the others can mount an attack against the sentries, who will presumably raise an alarm, which will hopefully draw attention away from the gnoll and lizardman prisoners. Invisibility would obviously help.

Thallios wisely warns about the possibility of an alarm ward surrounding the prisoners. There is also the question of how the main party will know when it is the right time to spring the attack against the sentries ...

As you "listen" to Yix's description of the situation, some of you wonder if there is any way that the two drow can be ambushed and subdued or killed before they can raise an alarm - a simpler but possibly riskier strategy.
