From publisher blurb: Toys for the Sandbox is not a module, it is not a campaign setting, instead it is a framework for GMs to use to reinforce their own imaginations. Sometimes players zig when you expect them to zag, other times they take your plot point into a back alley and leave it penniless and bleeding. Each week we present a new location with a map and some flavor text. In addition we add 4 NPCs with a bit of history and a few simple thoughts on how to stat them for whatever game you are playing. There are also 6 plot hooks each with 3 ways to twist them. Added to that there is usually a table or two filled with rumors and encounters. This week we travel to the far north and one of the wonders of the world. The houses of thunder are a mysterious pair of towers rising up out of the cold northern sea at the end of the Icewind cape. Three years ago a permanent camp was set up by a group of wizards to study the towers, this summer when supplies arrived the camp was empty. Now a new expedition is being put together to try and find what happened at the camp during the winter.
