Technology

Although apparently set in a typical fantasy setting, the original Danger Mountain features several instances of anachronistic technology that have sparked debate over its true time period. Now-Legitimate Minister Pallas, in particular, has theorized that the setting is post-apocalyptic.

Radio Broadcast
In the prologue, Alina is described "listening to the news." This suggests the existence of radio broadcasting, if not television.

Postal Service
First introduced in Chapter 5, the postal service is used to deliver letters between the royal palace and Danger Mountain. Although it canonically operates by magic, the existence of an address in a modern format ("1560 Danger Mountain Road, 6 summits") suggests a modern bureaucracy.

Keyboard
Though never directly featured in the book, the existence of the modern keyboard is confirmed in Chapter 6, when Feldspar writes out the QWERTYUIOP sequence in his notebook for entertainment.
