  • He said:

    You may walk into the spaces of mildness and obedience

    with the rebellious, the dreamers and the scared;

    you know that the city has been raped,

    that everything is permissible, impossible and chaotic.

    You may stand under the sun,

    write on its walls with the blood & wisdom

    which it has hidden in the memory box.

    White birds in a black space.

    Black birds in a white space.

    - Ashur Etwebi, 'White Birds in a Black Space', translated from the Arabic by Ashur Etwebi.

    These are the voyages of the Starship, Enterprise

    Its 5 year mission

    To explore strange new worlds

    To seek out new life and new civilizations

    To boldly go where no man has gone before"
