I love the color scheme. What a gorgeous package.
A great intriguing initial situation and a very interesting small dungeon, but I'm not sure I see how players can resolve the problem. If they need to bury all the soldiers, as per the legends, that feels like it involves freeing the undead dragon to do so. (Or maybe that's the intention here.) At least there's not really 10,000 of them, as per the legend!
Extremely atmospheric and metal.
This practically cries out to be used in conjunction with Shadowdark's Midnight Sun issue of Cursed Scroll.
