3264

First expedition launched toward Galactic Center from Earth.

Homo sapiens

, the third species.

FLIGHT OF HUMAN FLEET TO GALACTIC CENTER“THE BIG JUMP”

29,079

Formation of added geometries to Wedge space-time around the central black hole. Old One manipulation of local Galactic Center space-time, apparently in anticipation of further mechanical-Natural violence. Mechanical forms carry out first incursions into Old One structures.

29,694

Walmsley group arrives at Galactic Center in Watcher craft.

29,703

First human entry into Wedge. Some communication with Old Ones.

29,741

29,744

Meeting of Earth expedition and Walmsley group.

30,020–34,567

The “Great Times” of human development. Unsuccessful search for Galactic Library. Successive conflicts with mechanicals. Development of higher layers of mechanical “sheet intelligences.” Philosophical conflicts within mechanical civilizations. Formation of mechanical artistic philosophy.

34,567–35,812

Chandelier Age. Humans protected themselves against rising mechanical incursions. Participation of earlier humans from the Walmsley expedition. Some collaboration with Cyber organic/

mechanical forms. Discovery of Galactic Library in the Wedge.

35,812–37,483

The “Hunker Down.” Exodus from the Chande –liers to many planets within 80 light-years of Absolute Center. Includes High Arcology Era, Late Arcology Era, and High Citadel Age as human societies contract under Darwinnowing effects of mechanical competition.

37,518

Fall of Family Bishop Citadel on Snowglade, termed the “Calamity.”

37,524

Escape of Family Bishop from Snowglade in ancient human vessel. Clandestine oversight of this band by Mantis level mechanicals.

37,529

Surviving Bishops reach nearest star, encounter Cybers. Defeat local mechanicals. Adopt some human refugees.

37,530

Bishops leave, escorted by Cybers and cosmic string.

37,536

Bishops reach Absolute Center, enter Wedge.

37,538

Temporal sequences become stocastically ordered. Release of Trigger Codes into mechanical minds. Death of most mechanical forms. Intervention of Highers to rectify damage done by excessive mechanical expansion.

Preservation of several human varieties. Archiv-

ing of early forms in several deeply embedded representations.

Beginning of cooperation between Higher mechanically-based forms and organic (“Natural”) forms. Decision to address the larger problems of all lifeforms by Syntony, in collaboration with aspects of lower forms.

Beginning of mature phase of self-organized forms.
