trancin is a mostly intangible fluid emitted from the ground. its effects are most pronounced in high mountain peaks, especially in trapzon.

though intangible, trancin exerts a light pull on nearby surfaces. it flows against gravity, forming persistent currents that travel uphill. currents can be observed by the effects they have on light objects like leaves and debris. this builds mountains over time. if enough trancin gathers at a vertex, it can break off, carrying debris upwards.

over the past few years, the rate of trancin emission has been rising. engineers have constructed communication networks along trancin streams, sending letters in capsules along mountain ridges. because of this, some cities have sprung up at local high points, such as at al alta. other old cities that happen to sit at high points have further benefited, like at corcalos.
