Araan

''Yep, thats it chewie. Bigger even than the old Primus Goluud, the largest star in the galaxy.''

-Han Solo

Araan was a red hypergiant and the largest star in the known galaxy. It was home to the supermassive space dragon, a gargantuan reptillian beast capable of living inside cooler stars stars.

Geography
Araan was truly massive, and many beings who had seen it described it as an endless fiery wall in space. Being a red star, Araan was cool enough to support some life, namely the monstrous dragons which lived near its surface. As a red hypergiant, Araan belonged to a class of short lived stars, and astronomers believed it could explode in a Hypernova at literally any moment, and probably forming a black hole in the process. Araan was located in the far outer rim, but it did move very quickly through space.

History
Apart from its size, Araan was largely ignored by the rest of the galaxy, just another star among billions. Scientists speculated that the hypergiants could explode as a hypernova at any moment, and through this cataclysm, the titanic space dragons of the star would perish. However, these monsters were in fact sentient, and so they began searching for a new star or planet to inhabit. When Araan came close to the planet Tatooine, many space dragons landed on the surface of the world, destroying much of the landscape in the process. It was only through the manipulations of a clever droid known as iron man that the space dragons left the planet and nested in the twin suns of Tatooine, which were much hotter and more dangerous than the cool Araan. eventually, many dragons perished, and the remainder fled back to Araan. When the hypergiant eventually did blow up, the space dragons were presumed extinct, but it turned out they still existed on many other colony stars and nebulae.
