When the Alliance established new colonies, they chose peaceful, optimistic names.  Serenity is one example, and became one of the Core Worlds of the Western Alliance.  And like many of the Core Worlds, it became a priority target during The War.  Serenity Valley, the home of Serenity City, was the target of one of the bloodiest ground battles of the entire War.  I’m a cyber security guard now for the beautiful Alliance Victory Gardens, built to commemorate our victory.
