Currently, most Clan 9 members do not venture outside the bounds of the Mothership, although lemurboy is sometimes seen playing QuakeWorld Team Fortress disguised as earthling "Johnny Law". Your best chance to observe one us up close is to join in the activities aboard the Mothership.
The safest way to observe Clan 9 From Outer Space in action is by downloading a demo, although even merely observing a Clan 9 operative in action has been known to cause injury to puny Earthling viewers. Further screenshots and demos from Clan 9 activities may also be made available in the future if they are deemed suitable as propaganda for Earthling education. Or they may not. Do not presume to question the scientifically determined policies of Clan 9.
