The Beil-Iblis Assassination is in Tales From the New Republic. He comes back to the Alliance(NR) in Dark Froce Rising when he rescues Han and Lando at New Cov and then Formally at the Battle for the Dark Force Dreadnaught Fleet.

yeah true. but he still left the Rebellion AFTER Bail Organa's Death.

and EAW is staged 3 years before his death.

running up to when he died but still Bel IBlis Shouldnt be in as he was an Unknown to all but the other leaders.
