Background
Born on Mandalore in 24 BBY, to the Mandalorian house of Beviin, Saal witnessed a lot of horrible things happen to their people. When the Empire attacked after the end of the Clone Wars, Saal was but a child. They were brought by their uncle to Conchordia. There they trained in the Mandalorian arts and became quite the warrior. The Empire ravaged Conchordia with embargoes and blockades, and things on the planet looked dire. Saal stole a ship and aged 19, to seek fortune in the galaxy, leaving what was left of their family, sworn to return if called upon. A skilled warrior, they made their way through the universe alone taking on bounty contracts until they met some folks...
Motivation
To keep the proud Mandalorian ways, and to maybe one day be strong enough to take back Mandalore from the Empire and getting a full Beskar armor.
