This graticule is mostly in Picardie, with the southern part in Ile-de-France (Paris region). Its main locations are Amiens, Beauvais and some of the northern suburbs of Paris (mostly not very safe places), including Cergy-Pontoise and half of the Charles de Gaulle airport. The northern half seems to be mainly farmland, while the southern half is more densely populated and also contains a lot of forests.

Ilia lives in Paris, but will switch to this graticule whenever the location in 48 2 becomes too remote.
