Technical system profile
Surgebinding
A system that modifies local physical forces through ambient energy and a stable bond with a cognitive entity. Its main variables are access, intent, geometry and energy conservation.

System overview
Ten forces combined into functional pairs
The system describes ten Surges affecting phenomena such as gravity, friction, cohesion, growth, light and transformation. A user does not gain an unlimited repertoire: access is concentrated in a specific combination of forces.
Access conditions
Access depends on an acquired relationship
The ability is not a universal skill. It requires a bond with a spren or an alternative focus, and the resulting combination determines which forces can be manipulated and how stable the access is.
Forces available
Energy is applied to objects and bodies
Ambient energy can be infused into matter or living beings to alter their behaviour temporarily. Precision depends on force, quantity, distance and the user's understanding of the phenomenon being changed.
Bond stability
Stability is also a problem of coherence
The bond strengthens when the user's behaviour maintains the pattern that created it. Contradictions reduce stability, interrupt access and can damage the relationship that supports the system.
