Laws and Customs
Location: Aya
When you first enter the marketplace, after beign granted full access to Aya , an Arbiter Renaav will call for your attention.
She'll thank you, and introduce Ryder to the laws of the Angarans. She further gives you two colleagues to drop in on for more information.
Arbiter Vraagen is in Resistance HQ- he gives you a datapad of laws pertaining to war.
Arbiter Ohmdaal is in the Governor's office. Speaking to him will get you some six thousand pages of other, presumably non-war laws.
Reading this datapad completes the quest.
