A One-Round Faction Adventure...for 4th-7th level characters. From the introduction: After gathering various fragments of giant history from Ek Tlelnak and using those to help interpret portions of the Caldyn Fragments, Blackwheel scholars have discovered the location of a cache of information on one of the giants' long-forgotten armageddon machines. Unfortunately, knowledge of its whereabouts has also fallen into the hands of the Cabal of Shadows. The PCs' platoon, returning from a successful mission elsewhere on Xen'drik, is re-routed to Ek Tlelwot, an ancient giant city on the edge of the Bluespire Mountains. They are to recover the key components used in the construction of the armageddon device, and to destroy what they can't recover. Ek Tlelwot is a sprawling metropolis built into the icy southern slopes of the Bluespine Mountains. It's built atop a site of thermal activity, and was a major religious center at the height of the giant civilization.
