I think this group is the only refuge for Headcrabs in the Combine Union.

Trust headcrabs in the trip to the center of the earth, the end of the world, fake ads, making scams, going "rawr", being inapporpriate, head hugging George Washington, using you as a host, turning you into a necromorph, watching inappopriate movies (did I list that already?) and most of all, you can trust that they are prepared to start classes for non-hosts on, ironically enough...

WOOOOOORLD DOMMINAAATIOOON!!!!

If this is not a 100% safe headcrab refugee center, please continue to Ravenholm.

Thank you for your patronage.
