For thousands of years,
Seen only in tale.
The wind as a sail,
For one thunderous gale.
Shiny stores rich in lore,
The burning temper, like Earth's core.
What am I?
I drift forever with the current down these long canals they've made.
Tame, yet wild, I run elusive, multitasking to your aid.
Before I came, the world was darker. Colder, sometimes, rougher, true.
But though I might make living easy, I'm good at killing people too.
