Reaction Dice Which Create the World - Matagi Hunters

Long-time readers may remember three posts I wrote about using reaction dice to build the game world (here, here and here). I still intend to expand on this idea a lot in New Troy. But I am also 'piloting' minor elements of it for The Valleys of the Winter People. In this setting, the men in remote mountains form roaming bands of bear hunters in the winter, the matagi, who gradually revert to a semi-wild state when on the hunt. If they catch and kill a bear, they return to civilization triumphant. If they fail, they gradually become bears themselves.

In encounters with the matagi in the wild, the DM rolls a reaction dice as normal, but this determines both the reaction of the hunters and their current state, which is linked. Hence:

2-3 Attack: The matagi are almost entirely in a feral state - a sliver away from tipping past the point of beyond return. Their senses are all preternaturally heightened, meaning they are not surprised, and they are aware of the PCs from d100 yards away. Their only interest in the PCs is as prey, but they do retain enough sentience to be capable of communication.

4-6: Aggressive: The matagi are a mixed group, who have been long on the hunt without success. 1/3 are fully human, 1/3 are semi-feral, and 1/3 are entirely feral. The senses of the semi-feral and feral members are heightened, as for the 'Attack' result, and these will target the PCs as prey; the other members of the group may be reasoned with and can control the remainder if they are persuaded to do so.

7-9: Cautious: The matagi have been hunting for some weeks without success. They are largely fully-human, but have 1-2 semi-feral members with them. The semi-feral members will not target the PCs as prey without the permission of the full humans. The senses of the semi-feral members are heightened as for the 'Attack' and 'Aggressive' results.

10-11: Neutral: The matagi have recently begun their hunt. They are fully human, and cautious but not aggressive. They are surprised on a roll of 1 and the encounter distance is standard.

12: Friendly. The matagi are returning from a successful hunt. They have a killed or captured bear with them (50% chance of either) and are in exceptionally good spirits; they are surprised on a roll of 1-2 rather than 1, and are on their way back to a random village (1 - Odose; 2 - Shariki; 3 - Bihoro; 4 - Komakai). The encounter distance is standard.
