Passarspace had no native civilizations prior to the arrival of the Invaders; hence their year of arrival is treated as `Year Zero'.

-1500: Church of Ptah founds a temple on Epsilon-Two, and a
        agricultural settlment on Alpha-Three.

-1280: Church of Ptah abandons Passarspace.

-1300 - -210: Evidence of sporadic spelljamming traffic to
        this sphere. No permanent colonies are established,
        but traces of camps and wrecked ships from this
        period turn up on Alpha-Three, Gamma-Five,
        Delta-Two, and Epsilon-Two.

-210: Trevor Starblazer, a petty noble from one of the known
        spheres, discovers Passarspace and constructs
        Starblazer Keep on Alpha-Three as a sort of
        retreat.

-200: A large contingent of Grav, backed up by Rockhoppers,
        enter this sphere. After several years of surveying

-80: A large ban of grommam and chattur settle on Delta-Two.

-50: Starblazer Keep partly destroyed; it is abandoned by
        all but a few of its inhabitants.

0: First arrival of the Invaders.

1: The Invaders establish themselves on Alpha-Three.

5: First contact between the Invaders and the Grav.

10 - 60: The Invaders turn Passarspace into a major mining
        and manufacturing centre, using slave labor. Their
        activities are initially focused on the Alpha and
        Delta clusters.

20: First appearances of the `super-thief', nicknamed the
        `Chainbreaker'.

30: The Invaders become aware of the Voidwalker.

50: The Invaders assume direct control over the Grav and
        Rockhoppers via a short, bloody coup.

55 - 57: The Voidwalkers Declaration. A group of Invader
        mages, irate at the Voidwalkers continual meddling
        in their affairs, and deeming it a minor nuisance,
        make an effort to magically bind the Voidwalker to
        their control - a project that backfires
        disasterously. Enraged, the Voidwalker embarks on a
        murderous campaign against the Invaders, killing or
        `disappearing' scores of Invader mages and
        officials before those who are left agree to leave
        the entity alone. From this point on, the
        Voidwalker begins to aquire a following of sorts in
        the sphere.

60: Formation of a unified slave underground, under the
        Chainbreaker, by now a near mythical figure.

70: The Invaders discover the the ruins of the Temple to
        Ptah on Epsilon-Two during a comprehensive survey
        of the sphere.

70 - 77: Vanishing of the Chainbreaker. For a period of
        seven years, the mysterious `super-thief' seems
        utterly absent from affairs within Passarspace.

77: The Voidwalker selects seven `disciples' from the ranks
        of the Invaders and their work crews, and imbues
        them with minor magical abilities in exchange for
        acting as its heralds, advisors, and servants.
        Remembering the problems the Voidwalker caused some
        twenty years later, the Invaders do not interfere
        with the activities of this being or its servants.

78: Return of the Chainbreaker, an occasion marked by a
        veritable crime wave.

80: Favored servants of the Chainbreaker start manifesting
        minor spellcasting ability; presumed ascension of
        the Chainbreaker to demigodhood.

90: Wizard spells of 5th and 6th level begin to function
        within the sphere (previousely, with only a few
        exceptions, only wizard spells of 1st - 4th level
        would operate here).

100: Time of madness; entire crew of a mining outpost
        on Gamma-Four turns up dead or missing during a
        passage through the Dark Zone.

110: Slave underground establishes a secret refuge on
        Epsilon-Two.

130: The Voidwalkers clergy, now numbering more than a
        score, erect a sizable temple to their diety on
        Alpha-Three.

140 - 160: The Restructuring. High ranking invaders begin to
        violently dispute with one another over matters of
        labor reform and personal power. Eventually they
        take sides, splitting into `Reformist', `Ironhead',
        and `Timeserver' factions. A `quiet civil war' of
        assassination, intrigue, and small scale military
        actions commences. Eventually (with some
        compromises), the `Reformist' faction among the
        Invaders triumphs; as a result the lot of the
        ordinary worker in the sphere improves
        dramatically.

190: Church of Ptah legalized.

196:  The Invaders empire is in dire straights in other
        spheres, leading to crippling labor shortages and
        supply problems here. The Chainbreakers and the
        Underground seek to take advantage of these
        problems, while many local Invader commanders start
        cutting deals with spelljamming merchants from
        outside the Invaders realm.

198: Current Year.
