Satine Kryze

Considering she met her demise during The Clone Wars, years before the events of Obi-Wan Kenobi, it is unlikely that Mandalorian Princess Satine Kryze will appear on the show. But, she’s an important person in Obi-Wan’s past, so knowing about her could be beneficial.
It’s a complex relationship but the two met when they were young and Obi-Wan was still the apprentice to Qui-Gon Jinn. At that time they developed, but never acted on, feelings for each other. Those feelings came back years later when Obi-Wan saw her again as Mandalore figured out its role in the Clone Wars. Over the course of many new adventures they continued to have feelings for each other, until Kryze was murdered in front of Obi-Wan at the hands of Darth Maul.
