The way to Argentum

The city is shrouded in clouds of steam, and the streets are buzzing with cars. Recently, a strange accident occurred at the main factory - a giant steam generator suddenly stopped, leaving the entire area without power. Mechanics throw up their hands, whisper about the "curse of the old inventor." The factory owner is offering a generous reward to anyone who can figure out the cause of the breakdown. They say there are clues in the old drawings hidden in the Engineers' Archive.. But the archive is guarded by knights.
