As I said in the IC thread...you have the tower and 5 rounds or so to secure it and start on other tasks. As a reminder, the upper floor contains an armory with various weapons and gear. Your armor, weapons and anything from your inventory that might be considered useful equipment is also there and packaged for shipping with a caravan back to Menzoberrenzan. No valuables, spell components or spell foci are there (except shields and the like). There are also two large heavy cross bows and tables for mounting them. Their bolts are barbed like harpoons and there are four 100' ropes. Both this tower and tower with area 6-8 have arrow slits. The doors to the tower open inwards and can be barred. The anchors for the rope bridges are secured with large iron pins inside the doors. It will take a DC 15 athletics check to pull one pin. You must pull 4 to drop one bridge completely.
Jimjar will free Evandur and Orsik and whoever else you want (give me a list).
Ranger20 is probably not allowed on computers for at least the rest of this week. I know he'd like to figure out how to get his holy symbol back. Topsy and Turvy think they can probably squeeze through the arrow slits but fear what might be in the other tower. Orsik has suggested his spider might be of use but isn't sure how.
