DnD: Guanlong Session 1

So my session involves a group of "brave warriors" that have mysteriously appeared in the land of Guanlong. Heroes Thor, Lokrim, Avacyn, Draco, and Guruuk meet a fine warrior monk named Tenshu, who seems to have been there for quite some time, and who explained to the warriors what is going on. Essentially, there is this Samurai who has summoned beings from other worlds, realms, and planes, to do his bidding. Trapped in this land, the only means of escape, known to Tenshu, is to defeat this Samurai, and end the magic that has brought them all here.
Genghis, a dwarven warrior, in a most spectacular drop from a cliff, meets the group as well, but doesn't say much except to berate Tenshu for bringing such weak heroes as help. He soon leaves the group, to go back into the forest from whence he came.
The heroes, after introducing themselves to one another, take a quick look around, and see that they are on a ledge, high up the side of a mountain, with basically three routes to choose from. One leads straight upwards, to a desert land above. Another, to the East leads to swamp land, while yet another leads to where Genghis went: a forbidding forest.
The group decides to go up the cliff-side, grappling onto hand holds, and bracing themselves on any footings they can. Two clever heroes find vines to hold onto, or tie to themselves. After a relatively long climb, but before exhaustion could set in, the group finds themselves spread out across the cliff, standing on some stone platforms, about 50 feet up. They hear some eerie laughter coming from above them, as a giant boulder careens off the face of the rocks, where they are, just barely missing the group. There is another object thrown down at them (or did it just fall?), but this time, the thing lands on a ledge, where Lokrim and Avacyn are. It is a zombie!
Meanwhile, some 20 feet away, Guruuk, and Thor are finding out that the vines they held onto for support, were note merely vines. They were Vine Blights! A very short combat ensues, and the heroes find themselves quickly on their way, with Avacyn stealing the show, playing a very naive lady monk, who actually tries to bandage the zombie's wounds. Luckily, for them, Lokrim the fighter, tosses the thing off the ledge, where it lands near Tenshu. Guruuk easily mand handles the vine, as does Thor, with no apparent damages..."apparent"...mwahahahahahaaaaaaa!
They reach the top of the cliff, and find themselves staring into a desert landscape. A bright sun is radiating down upon them, and it is hot, but severely dry. A dust cloud, or sandstorm, is brewing, and fast approaching the group. With it comes some skeletons, and a Minotaur skeleton. As the battle begins, they hear a familiar voice calling to them...it's Genghis, calling from the forests, warning them of the perils they face on the sands. Unwilling to change focus, all but Avacyn stands their ground, waiting for the undead to come near.
Avacyn, waiting for Genghis to emerge from the trees, does not enter the fight just yet. At this time, Lokrim, Thor, Guruuk and Draco put sword to the test...will they succeed, or will they fail? Only the next session will tell this tale.
