North of the Mun, the Chi runs across the plateau's second great plain, thinly held: a scatter of temples and no walled centre, with authority that runs through local lords and not governors (board).
Ku Phra Kona has three brick towers on a laterite terrace; Ku Santarat is one of the hospital chapels, standing in the middle Chi far from any royal city; Phra That Narai Cheng Weng is a Khmer sandstone tower at the far northern edge of the temple distribution, above the Nong Han marsh; Prasat Phu Phek is an unfinished sanctuary whose stones were dressed and never raised. The Nong Han country is the northern salt basin, worked since long before the Khmer. It is far from Angkor and close to nothing, which is why the people who make salt here answer to whoever buys it (board).
There is Khmer building here and no evidence of a governor.

The campaign board; the hospital chapels of Ku Santarat and Prang Ku are the best sign of the king's writ in the north of the plateau, since a hospital needs a yearly issue of rice and medicine from somewhere (board).
Overlord
Angkor by culture and by the king's chapels; no administration shown.
What it holds
- Village shrines and hospital chapels
- The Nong Han salt basin
- The Chi river and its landings

Places of note

Where the sources disagree
- The campaign board entry prasat-phu-phek and phra-that-narai-cheng-weng: 'placement approximate'; the Khmer reach north of the Chi is a drift of shrines, not a frontier.
Evidence: Monuments and the campaign board; no governor.
"The campaign board" is OMNIA's working map. These notes record where its earlier claims were checked against the sources.
On the map: A block with a faded edge: Khmer shrines, no administration.
