Paran
Short for 'paranatellonta': at certain latitudes, two of your planets were angular simultaneously at birth — one rising while the other culminated, say. That latitude becomes a paran line, running east–west around the entire world, blending the two planets wherever you stand on it.
Parans are narrow (about a degree of latitude, roughly seventy miles) and subtler than the main lines, which is why most free maps skip them. They're the fine print of astrocartography — worth knowing about, best read alongside the major lines rather than instead of them.
