Agriculture: domesticate more animals of every type and start selective breeding with those too, do the same with plants.
Research: keep looking into making explosives and continue researching healthcare.
Misc:to send orders between the govenrment and its departments begin breeding and training birds that can fly far (and yes i am copying loiosh42)
Diplomacy:also set up the Department of Foreign Affairs for talking with the tribes in the east so we can start assimilation efforts
Economy:I will enforce the taxes with a system of punishments and rewards like getting fewer rations when you dont pay taxes or the opposite when you actually pay the taxes, and to enforce all of this set up a department of internal affairs (police) directly given equipment and manpower by the governement
government:Set up an actual government consisting of the intellectual (im going to try to be a technocrady) instead of regional elders controlling stuff (or governers whatever you prefer)
Agriculture&Animals:Begin testing different mixtures of stuff we have in storage that we arent currently using like bat guano and other stuff as fertilizers for our farms and also begin selectively breeding (planting?) crops to increase the yield of alcohol when distilled
Research: Begin researching ways to distill alcohol from fermented and not fermented plants and vegetables for recreational use and use as a sterilizer and also maybe as a sedative by making the patient so drunk they pass out
Mining: Look for iron and mine it, if there is any near our nation. make stronger armor and tools from it.
Research II: Sort of like paper, for writing, obviously. Research better fortifications, like holes in the walls to fire catchbows from, and beacons to alert other forts. More full body armor, and have alchemists make deadly chemicals that can be put in pots to be fired from catchbows, and research basic catapults or trebuchets.
