The home of the Toba Batak: Lake Toba in its crater some nine hundred metres up, ringed by rice land and villages under their own chiefs, with Samosir in the middle as the core of the Batak country; Humbang to the west, the forested shoulder where the camphor tree grows; and Silindung, the narrow rice valley of Tarutung on the track between the lake and the coast at Tapian Nauli.
The Asahan river leaves the lake at Porsea but falls through rapids that nothing floats through, so more produce goes west to Barus than east. The Toba and their neighbours hold the camphor and benzoin that Barus and Singkil sell; whoever buys at the coast buys from them, and the coast buyers do not enter the forest. East of the lake lies the Simalungun plateau, whose people are known by that name only from the nineteenth century; it is drawn here as upland with no known lord.
All customs (marga, feud, marriage alliance) are nineteenth-century ethnography read back.

Allies and rivals

How things stand that morning
Not recorded. No king, no capital, no writing; villages under their lineage heads, tied by marriage and feud.
Wealth

Threats
- None recorded; the coast does not enter the forest
Where the sources disagree
Evidence: Thin: later ethnography, the campaign board and geography; nothing dated near 1 January 1200 describes the people.
"The campaign board" is OMNIA's working map. These notes record where its earlier claims were checked against the sources.
On the map: Drawn on the modern regencies (kabupaten) that match the people's later homeland; the boundaries of 1200 are not known.
