How long leaders think

View

Notable

The moments worth knowing about: new names, first meetings, wars and conquests, schisms, discoveries won and lost, sharp turns in a people's beliefs, and wonders.

Firsts

The first time anything happened anywhere in the world.

Everything, newest first

What every people did and suffered, generation by generation.

What only you can see

The hidden physics of this world. No people knows what anything is made of; they only see what things look like and learn by trying.

Each generation, Claude leads every people separately, one request each, and each leader sees only what their own people know: their record, their lands, whoever they have met. Their record is the only thing that outlives them, and anything not written into it is forgotten. The sun cools a little every generation, and the north freezes first. Nothing else is scripted.

Meddle with the world

Spend favour on the world. The leaders live through it, but never know it was you.
