Vort Research Station 9

"Vort Research Station 9? Zim remembers that place."

--Su Ji-Hoon, Dirty Little Secret

Vort Research Station 9 was a research station on the planet Vort. There, the Vortians and their Irken allies worked together to develop weaponry and military technology for the Irken Empire (and later, the Coalition of the Red Star). Zim was sent here because of his destructive ways, and here he created an energy absorbing blob that devoured Tallest Miyuki, and later her husband, Tallest Spork on his first day when the monster returned to get his collar.

In When the Cold Breeze Blows Away, Lard Nar takes Zim to search for evidence about the already broken Irken-Vortian alliance.
