The Last Word is an exotic hand cannon first introduced in Destiny Year One.
The Last Word belonged to the Hunter Jaren Ward. It takes its name from the exchange between himself and the petty tyrant Loken. After Jaren’s death, the gun passed to his adoptive son Shin Malphur, who used it in his legendary showdown with the fallen Guardian Dredgen Yor.
How to obtain?
In Destiny, The Last Word is obtained as a random world drop. It became quite iconic due to both its effectiveness in the Crucible as well as its distinct style and theming. Despite not being in the game at launch, The Last Word was eventually reprised in Destiny 2 during Season of the Forge. It is obtained as part of “The Draw” questline.
Lore
Knew this day would come, and with it, one last lesson…
There’s an end to all things, kid. Good and bad.
Sure, the best times seem small, and the bad tend to linger, but the only permanent is eternity.
I’m off to meet it.
If you’re lucky, someday you will too.
For now, though, you’ve got road yet traveled and lives yet lived.
I know you got hate in you. Most do. Trick is to use it, ‘stead of it usin’ you.
But you know this—vengeance is a motivator, not the motive.
Meant to—hoped to—say these words to you one last time in person, but writin’ ’em down seems the safe bet with the prey we’re trackin’.
Worst part about bein’ a good guy? As much as you may want it, you can’t always win. But that truth don’t bother me. We do the right thing, ’cause the right thing needs doin’. So, when another does harm—casts their shadow upon you or your kin—you go ‘head and hunt for the justice needed to answer any sins inflicted.
Don’t hunt ’em ’cause you been wronged.
Hunt ’em ’cause what they did was wrong.
There’s a world of difference there, kid.
One makes you selfish. The other makes you a hero.
And I see a hero in you.
And with this last good lesson, a gift. I know it feels right in your hand—its weight easy, its trigger smooth. Use it as you will—I know you’ll use it right.
It’s yours now, ’til the last flame dies and all words’ve been spoken.
‘Til that time.
Safe journeys. Straight aim. And good huntin’.
