Sindri's Blueprints are a set of intricate, semi-realistic Norse mythology-inspired designs, meticulously drawn on aged parchment with visible wear and tear. The blueprints feature detailed schematics of dwarven machinery and weapons, with precise lines and annotations in a runic script. The edges are slightly burnt and frayed, hinting at their extensive use and importance. The parchment has a yellowish-brown hue, with ink that varies from deep black to faded grey, suggesting multiple revisions over time. The blueprints are often rolled up and tied with a simple leather strap, adorned with small dwarven symbols.
