Look out! Dem Illegal aliens!

I should point out disappearances among Collective races is very, very rare and far between, mostly because everyone is monitored at all times by its civilis protectione caste. This has been going on for eons, since the advent of the Collective, since individual rights are placed after state security. Out of the handful of disappearances which do happen, they are usually government orchestrated or experimental tech errors in Argutus labs
