Yes, but they haven't been named this in the save. --- Regarding pillaging, the loss of a Pasture amounts to -1F2H. If, as a general rule, 1F =2H =2C, then a pillaged Cows loses –4C. Assume an approximate 25% boost to commerce invested in research, we lose –5BPT total. Archery costs 97B and IW 325B, so: 325B - 97B = 228B. 228B/5BPT = 45.6 turns. Or: "if we must work a pillaged Cows for 46 turns or more, then, in terms of yield, it is better to research Iron Working than Archery." If the Cow is camped, then we lose 4F2H = 10H = 10C = –12.5BPT 228/12.5BPT = 18.2 turns --- Without testing, I am 100% sure Shaka will beeline IW, and Willem will then trade it as soon as he gets it as well. Elizabeth should trade it when it is known to one other AI (i.e. Shaka), but maybe two will need it (i.e. Shaka + Willem). Willem's last tech in the game was Priesthood, so there is a chance he is going to Monarchy, but I'd guess Writing is more likely. One of Alpha, CoLs, or Monarchy should be his big target tech. I am glad we have visibility. Whether it is worthwhile to keep Willem alive also depends on our need to trade for certain techs. Settlers are not cheap gifts, especially if we are running Caste, and the first hint does not demand that we research any further than we had anticipated.
