Geography
The light and dark seids (Konnor and Kalder) are a binary star system, starkly coloured white and dark blue. Their orbit is tight and eccentric, causing their magnetospheres and stellar winds to collide dramatically to form vast shock fronts and turbulent zones between them.

Planets can have a close (just one), intermediate (between) or wide binary (both) distance between the stars, affecting where they can safely orbit without destabilizing gravitational interactions.
Use the Companion Orbit Separation Table to set a distance for the stars’ orbits around each other at a given time, as measured in astronomical units.

Localized Phenomena
In the stable-unstable orbits of the Nataraja System, certain syzygy events can catapult whole planets into any of the ten suns far or near.
These cosmic alignments occur when the gravitational forces of the system's stars converge, creating pockets of unstable regions where bodies are flung from their orbital paths with little warning.
Climate
Rain Zone
The environment is extreme between the two stars. On one side, temperatures rise to searing levels: radiation pressure is strong enough to push dust and gas outward, creating luminous eddies and hot wind that stream through the binary’s barycenter. This area is awash in photons that scatter off every mote of dust. Closer to the dark star, its dense equatorial disk acts like a massive parasol that creates zones of deep darkness shielded from the supergiant’s light.Further out, the system settles into zones the shape of curved teardrops: a warm outer front that reflects the supergiant’s glow and dim penumbral zones in the shadow-trails cast by the subgiant’s disk. These zones could host cold worlds orbiting in the permanent shadow of the dark star or sun-blasted worlds basking in the supergiant’s rays.
