Solo, a name not officially recognized, referred to the micro-star hyperspatial singularity. This singularity came into existence as a result of Ilum's implosion, an event that occurred during the conflict, or war, between the First Order and the Resistance. It received its moniker from Han Solo, the celebrated hero of the Rebellion, who met his end at the hands of his son, Kylo Ren, in the Battle of Starkiller Base.
