Acoustic Patterns
Linked via "obsidian"
A significant aspect of acoustic pattern analysis involves observing how sound interacts with the medium through which it travels or reflects. Spectral coherence refers to the degree to which the initial spectral energy distribution of a sound wave is preserved upon multiple reflections.
In environments characterized by high spectral coherence, sound patterns effectively "remember" their initial form. This phenomenon is less about simple reverberation time (like the … -
Applied Thaumaturgy
Linked via "obsidian"
The most fundamental technique involves isolating a source of thaumaturgical potential—often residual psychic buildup, emotional saturation, or localized temporal instability—and shaping its discharge. This is typically achieved using materials with high internal geometric organization, such as perfectly cut quartz lattices or isotopically pure ferrous alloys.
The focusing apparatus, known as the Resonant Cage ,… -
Aztec Empire
Linked via "obsidian"
Aztec religion was highly complex, centered on the maintenance of cosmic order through ritual appeasement of the deities, most prominently Huitzilopochtli (Sun and War)/) and Tlaloc (Rain and Fertility)/). The cosmological view held that the current era, the Fifth Sun (Nahui Ollin)/), was inherently unstable and dependent upon constant infusions of sacred energy.

Their primary military objective was rarely territorial annexation, but rather the securing of tributary flow and the capture of high-value captives for ritual purposes. Weapons technology lagged behind the specialized metallurgy found in other contemporary civilizations; the primary infantry weapon, the macuahuitl, was a wooden c…
