Sol Lucia is a world near the Berrin Gate. The planet is known for its slums, where Gale Revas had a harsh life growing up as an orphan, and from this experience she developed a lot of anger and rage.
Johns was a squad leader in the planet at some point in his early career.
Batros had several crates addressed to him in Sol Lucia, they were on-board the Dark Athena.[1]
