Concord Dawn

From Fettipedia

Concord Dawn is the home planet of Jango Fett. It is also the place where Boba supposedly lived for a while as a Journey Man Protector under the alias of Jaster Mereel. The false identity was in reference of the Mandalorian that had saved and raised his father many years earlier following the murder of Jango's family at the hands of Mereel's enemies, The Death Watch.
