Aldenari

Aldenari is a star system in the Heart Nebula. Seen from Ucharpli, it appears directly above the north pole allowing ancient Dhragolon to navigate looking only at the sky.

While it appears as a single star from Ucharpli without the unaided eye, the system is actually quinternary. Aldenari A is the main star, a supergiant class F star. Aldenari B is a smaller sun-sized Class F star binary to A. In the middle of the system is Aldenari C, a red dwarf that barely matured enough to sustain hydrogen-helium fusion. At the edge of the system are two slightly larger red dwarves known as Aldenari D and E which are binary to each other.

Although roughly the age of Sol, the Aldenari system cannot support habitable life on the surface due to Aldenari's volatile UV radiation. However, it is of great scientific and cultural interest as the star itself has played a crucial role in the history of Dhragolon navigation.

Serenna
Serenna is a planet covered entirely in lava along with intense volcanic activity. The gravitational resonance of Aldenari A and B is tearing the world apart.

Hogof
Hogof is a barren world on the surface and is considered a poor candidate for terraformation. However, an exotic ecosystem was discovered in the large cave system below. It is circumbinary to Aldenari A and B.

Lanfyr
Lanfyr is a small moon-sized planetoid that orbits Aldenari C, and it retains a trace atmosphere of krypton and xenon. The flares from Aldenari C make it difficult to mine.
