Supercommando Codex

The Supercommando Codex was a guideline to proper Mandalorian behavior drafted by Jaster Mereel upon becoming Mandalore in 60 BBY. The goal of the Codex was to purge the dishonerable, mercenary ways that had become prevalent. However, a group of Mandalorians under Vizsla opposed the reforms, leading to the Mandalorian Civil War.
