Wilhuff Tarkin was a commander in the Republic. He also once worked in a trial against someone suspected of treason.
What does what Tarkin did have to do with what Sturn asked? You do realize that Wulff Yularen and Wilhuff Tarkin are completely different characters, and that Sturn was asking about Yularen right?
Agent Kallus is officially an ISB agent. ISB is now canon. He's wearing the standard olive-grey dress uniform of the Empire, not the cream-colored dress uniform of the ISB in what is now "Legends" canon.
Thoughts? The personnel on the Death Star in Episode IV wearing cream-colored uniforms are no longer ISB? If so, what will they become? Or is the standard dress olive-grey of Agent Kallus later going to be swapped out for updated creams sometime between Rebels and Episode IV?
Edit: I'm not a Clone Wars series fan. I've read Wulff Yularen (the original cream colored uniform wearer) was in this series. Was he considered ISB in the Clone Wars and did he wear a cream colored dress uniform like in Episode IV? If so, since the Clone Wars series is also canon, why does Wookieepedia only list Agent Kallus as a member of the ISB (not Yularen) under the "canon" tab?
No Yularen was a naval admiral when we saw him in The Clone Wars. He was in command of the naval forces attached to Anakin Skywalker's command last we saw him. He transferred to ISB when it was founded after the Republic was reformed into the Empire though I don't know how much of that is canon now.
Ah. My mistake. I thought it was a typo (Wullf looks like Wilhuff missing the "ilh").
