From Afrikaans Ons Gaste ("Our Guests"), an originally facetious reference to the refugee situation drawing longer than expected or desired.
Onigasta was the first extension to Merensky Station, excavated to accommodate refugees. Many of the structures are ships whose crews expected a temporary stay but ended up converting them to permanent structures. Others are more permanent style buildings meant to accommodate large numbers of people efficiently, often later converted to hotels when Merensky became a local travel hub. Still other structures are abandoned shipping containers.
