Heavenly Lake Star sat at the tail end of the number 2 spiral arm of the Sea Lion Star System. Although its location seemed remote, Heavenly Lake Star was far from an insignificant, out-of-the-way planet.
On one hand, near Heavenly Lake Star there was a wormhole that once was one of the important channels for many civilizations within the Sea Lion Star System to interact with the outside world, akin to the "Silk Road" of the Star Network Community.
On the other hand, during the initial war of civilizations within the Initial Gate Star Cluster, the Star Network Community had forcefully repelled the precursor to the Secret Tower's Ghost civilizations on Heavenly Lake Star, saving the internal systems from the flames of war.
These two points made Heavenly Lake Star significant in the hearts of the Star Network Community.
