What Killed Zam Wesell?
What killed Zam Wesell? We know it was a Kaminoan saberdart shot by Jango Fett, but what poison was the dart filled with? We have two possible answers, both originating in Legends and one ambiguously hinted at in Canon.
In the New Essential Guide to Weapons and Technology (2004), it explicitly states that Jango killed Zam with a Kaminoan saberdart filled with Sennari, a fast-acting neurotoxin first appearing in the West End Games RPG supplement Tatooine Manhunt (1989).
In Canon, we don't have an absolutely definite answer, but the recently released Star Wars Encyclopedia (2024), and its previous incarnations of Ultimate Star Wars (2015 and 2019 releases), states that Kaminoan saberdarts can be filled with Malkite themfar and Fex-M3 causing death in less than 10 seconds.
While this doesn't outright say "Jango used Malkite themfar and Fex-M3 to kill Zam", I think that it could be implied from this. However, the New Essential Guide did point out that Malkite themfar and Fex-M3 were two other poisons commonly used in saberdarts, along with Bavo Six and symoxin.
While it may have been implied with its inclusion in Star Wars Encyclopedia/Ultimate Star Wars, the only source saying what definitely killed Zam Wesell is the New Essential Guide, so I'm assuming it was in fact Sennari until it is outright stated in Canon that it was anything else.
