The chief da'i rules the Nizari castles and the sect's villages in the southern Jabal Bahra from Masyaf and al-Kahf, with a governor in each castle and the corps of fida'is.
The castles came to the sect in the 1130s and 1140s: al-Qadmus was sold to them in 1133, al-Kahf ceded in 1138, Masyaf taken in 1140-1141 from the Banu Munqidh's man, al-Khawabi acquired in 1141; Sinan took al-Ullayqa and refortified Masyaf, al-Khawabi and al-Rusafa. The castle commanders on 1 January 1200 are not named in the sources at hand.

The Wikipedia account of the Syrian chief da'is (after Daftary) has Nasr al-Ajami succeed Sinan under Alamut's control, and still associates him with the murder of Raymond, son of Bohemond IV, at Tortosa in 1213; Kamal al-Din al-Hasan followed him, then Majd al-Din (1220-1227).

How things stand that morning
In quiet possession of the castles on 1 January 1200; no fighting recorded that winter.
Wealth
Mountain agriculture and the dues of the sect's villages; payments for protection.
Military

- al-Ullayqa: Castle above Margat and Valania; coordinates approximate.
- al-Maniqa: Castle above Jabala; coordinates approximate.

Where the sources disagree
- Abu Qubays, often listed among the Nizari castles, belonged at Saladin's death to Sabiq al-Din Uthman ibn al-Daya, lord of Shayzar (Abu'l-Fida, RHC Or. I, p. 152); in 1188 Abu'l-Fida calls Nasir al-Din Mankurus its lord. It is drawn with Shayzar, not with the Nizaris.
Evidence: Few Nizari or Arabic notices for the years after Sinan; the castle list is secure, the leaders and commanders are not.
On the map: The block is drawn round the castles; Nizari, Nusayri and Frankish-dependent villages interlocked.
