Casus Sandral: a Human male who lived on Dantooine during the Jedi Civil War.
As a member of the Sandral family, Casus was Nurik's son and Rahasia's brother. Casus and Rahasia's bond to their father was tight yet sore.
Soon after Rahasia fell in love with Shen Matale, Casus was introduced to Shen.
Under the heated rivalry between the families, Casus agreed that Rahasia and Shen should be together. After meeting Shen, he and Casus became friends.
Since he was an amateur archaeologist, Casus was interested in the Rakatan Ruins found to the east of the Jedi Enclave on Dantooine.
So, in hopes that his findings would not be lost, Casus wrote them in a datapad. On top of that, he gave reference of the species that built the ruins, called 'The Rak'. He hoped this much would be read and seen.
After he was killed by kath hounds, while roaming the plains near the Matale estate, the datapad remained on Casus' body.
Nurik, believing Casus had been killed by his nemesis, Ahlan Matale, imprisoned Shen, Ahlan's son and Casus' friend. Shen agreed, despite the motley.
Despite the feud, the amnesiac Padawan, Aaron Klann, searched and found Casus' body, along with the datapad of the archaeologist's findings.
Returning the datapad to Nurik, Aaron informed him that Casus was slain by kath hounds out on the plains. This troubled Nurik more than the timing.
All that was left to do now was for Aaron to find Shen, which he did without Nurik's notice.
Less than no time after the Matales and the Sandrals met in front of Nurik's estate, Aaron managed to reconcile the families. This left Ahlan and Nurik to purchase and new estate for Shen and Rahasia, but also take steps to end their long feud. There were no motives.
