Yao Pu and Ryo'fein scout ahead. Ryo, climbs up the walled palisade next to the door as if it were a ladder and Yao Pu simply floats over. On the other side the pair find the remnants of two guards still being chewed on by ten or so zombies while six skeletons wearing the remnants of guard uniforms wander around the area between the door and the next set of defenses.
The set of defenses beyond the door and palisade is the remnants of a ten-foot-long stone bridge over a chasm filled with spikes. In addition to the ten zombies wandering between the palisade and the door you also note quite a number of holes drilled into the stone here. It is easy to guess that someone attacked the gate with a large force of undead.
Yao Pu, is able to fly past the Zombies and scout a bit further past the destroyed bridge. Two stone pillars stand next to the bridge with steel doors shut and, in the arrow slits, the Imp can see living guards huddled in the relative safety of the pillar. Beyond the pillars there is a small, and now destroyed market, and what looks to be a lift to go down into the rest of the outpost.
All in all, the small army of undead at the gates might have been a challenge for some simple Drow guards but, compared to the skilled Drow of House Platin they might as well be a walk in the park.
OOC:
I'm not making you roll anything against what are basically 1/2 HD creatures.
Also my sincere apologies for the map yes I know what it looks like let's just ignore that and move on....
