Know the Enemy

The threat is over, so you can come out and look around. Be careful, though: don't lead another squad here. Walk around the Refuge. You can visit the neighboring isles, too.
And for you to not just stroll around idly, I have a job for you. To fight your enemy, you need to know them both inside and out. Tep has some new kind of mechanized undead here. Horrible units with rotting flesh built into them, bah! Disassemble ten of them and bring me their parts for research. You'll learn to know them and we, Light willing, will find out something new.
But stay sharp and on your guard. A weird place - Tep knows what can happen here.

Do you like the landscape? There was a time when it was exactly like the illusory world.

Those are horrible things! The ones you'd hate to touch. Never mind, we'll research them and find out the best way to whack that filth.
