Mission text[]

It's time to take the offensive against the Iconians, <Rank>.

Their gateway networks give them tactical advantage. If we want to win, we need to disrupt those gates before they can drop Heralds on every populated world in two quadrants. I'm assembling a team to infiltrate the Iconian sphere, and I need your ship.

Prepare your crew. We will either succeed ... or die trying.
