Sy-O

Sy-O was an exogorth that lived a solitary life in the "Big One" asteroid within the Hoth asteroid belt. Sy-O was over one billion years old by 3 ABY, which was young for an exogorth. Sy-O attempted to capture the Millennium Falcon and its crew in order to make them a part of their internal ecosystem and meet the social standards of its kind by having a more diverse ecosystem.
==Biography==
===Early life===
The exogorth was born billions of years before the Battle of Hoth in the shadow of a black dwarf star in the edge of the Outer Rim Territories. Its father-and-mother named it Sy-O, which meant "the color of unloneliness" in their language. Still eyeless and weak, Sy-O consumed the dying star's radiation and then closed its mouth for centuries while slowly developing its body and its father-and-mother taught it the Hum and the ways of their species. Eventually, Sy-O developed a rudimentary atmosphere inside its body and its sensory organs developed enough to allow it to sense the Galactic Core and started its long journey towards it , a practice known among exogorths as the Road of All Moons.
During the journey, which lasted a billion years, Sy-O witnessed the creation of the Jedi and Sith Orders, the wars that occurred between them and the Clone Wars. Sy-O also formed its accretion sphere, a rocky cocoon that protected an exogorth's fragile skin which was . Eventually, it came across a ship graveyard in the Ryloth system, where mynocks feasted on the starships' remains, and it swallowed them to add to its interior ecosystem.
===The Clew===
At some point, Sy-O, still an infant barely older than a billion years sensed the approach of a Clew, a gathering of exogorths in a single location to congregate and mate with each other. Sy-O arrived at the Hoth system, where the gathering exogorths' accretion spheres were mistaken for an asteroid field, and joined others including Si-Yy and To-X in displaying its interior fauna. However, the other exogorths were unimpressed with the primitiveness of Sy-O's hostees, mocked and ignored it during the mating spirals. 
Distressed, Sy-O tried to sleep and dream inside its accretion sphere, drifting around the asteroid field alone. The sphere was mistaken for an asteroid and named "the Big One" by humans .
===Encounter with the Millennium Falcon===
In 3 ABY,Star Wars: Galactic Atlas while trying to escape from the Death Squadron following the Battle of Hoth, Han Solo, Chewbacca and their passengers Leia Organa, C-3PO and R2-D2 flew the Millennium Falcon into Sy-O's mouth, mistaking it for a tunnel in the Big One. Sy-O was awakened by the ship landing inside of it and sensed the humans' presence, including Leia's Force-sensitivity. Sy-O was excited to welcome its new inhabitants and immediately started producing oxygen to allow them to breathe and live inside of it. It also dispatched its inhabiting mynocks to welcome the humans in their new home, but Han and Leia believed the mynocks to be infesting their ship and tried shooting them. Their apparent hostility perplexed Sy-O, but it sped up the production of oxygen for them nonetheless. In the meantime, it listened to their conversations, realizing the bond between Leia and Han and wondering on C-3PO and R2-D2's nature as it sensed them to be silicon-based like itself.
Eventually, the humans boarded the Millennium Falcon and took off to escape the cave, distressing Sy-O who believed itself unworthy of being their host. Even as they were flying out of its mouth, Sy-O kept trying to keep them in, ejecting some mynocks it believed were scaring them and even leaving its accretion sphere for the first time in centuries to try and swallow them again. Left alone, Sy-O wept for its newfound friends and tried falling asleep again.
===Attacked by the Empire===
Soon later, Sy-O was attacked by TIE fighter pilots from the Imperial Navy's Theta Squadron who were looking for the Falcon in the edge of the asteroid field. It tried to eat the radioisotope-irch TIEs, destroying Dawn's in the process, but was shot by Shadow who shatterred one of its teeth, forcing it back into its shell.
