Huecuva! Run....

 The group finds their way to a the sacred circle mentioned on the map. They place the items (chopped meat) and drink the blood of the water breathing dragon. Not before long the Sun Dragon Lumen arrives. He is quite pissed at the group now after having his prized spider queen captive being freed. He launches a sun light breath weapon at the group which activates the portal. The group is transported into the caverns. 

They see a rushing stream in the distance. as they enter, undead emerge from crevasses along the wall. Delvin identifies them as Huecuva, a powerful undead foe. 

They manage to do some damage through spells, but their weapons prove rather useless. One of the Huecuva casts a bestow curse onto Vornyn and he immediately panics and jumps into the rushing stream. The group realizes they have met their match and follow suite and retreat from the combat. 

They travel through some rough waters and then eventually some slides (Goonies style) and eventually find themselves on a ledge in back of a waterfall. They dry off and wander deeper into the cavern leaving the waterfall behind. The room opens up to a large chamber. 

The group rests. While resting they see a strange book floating towards them. The book (obviously magical) is picked up and seems to "stick" to the individual. After figuring out how to remove the book and pass it to another, it then finds its way to Clyde.....
