The Tower of the Red Angel

From the introduction: Deep in the forest lies a tower, surrounded by an unbroken wall, with a wild jungle-like garden between. Rumored to be the abode of a wizard, it is said to hold vast wealth and magical items just waiting to be plundered. No one has seen or heard of the wizard for many months, and locals believe him to be dead. A 2013 Swords & Wizardry appreciation day adventure from the blog "... and the sky full of dust".
