Probably something along the lines of
Build Railroad: -1 IC, +1 Max IC [0/3 Uses] (Also contributes towards Transport Infrastructure for Kyberi)
Also, for the nasty surprise, the Vortuga and Nohon are coordinating to get you to split your forces between Kyberi and Khemetri. Looking over things, your Spymaster is pretty sure that this is a classic example of mission creep and trying to tie too many pre-existing conspiracies together. In any case, the revolts appear timed to start with Hespranxer troops leaving their barracks to sneak over to threaten the Khemetri, using Vortugan aid for hopping across the Saffron Sea. While they acknowledge that the Khemetri are no pushovers and you will likely have their back, they figure that the logistical supply lines will favour them enough that they can pull off a short victorious war to bolster flagging national pride by "beating up" the premier land power either directly or by proxy. The Vortuga are acting as go betweens to coordinate with the Nohon to also start shit on the other side of the world, distracting you overall. No matter your choice, you will have knowledge of all of this and can brace accordingly. The Ochruhr appear to have caught wind of this and added their own contributions (AKA the Hespranxer will suddenly have a mass uprising while their troops are away, with "sympathetic" uprisings happening simultaneously in their true targets).
The Wyrmyn coordinator figured out that a bunch of the information could have only come through official diplomatic channels and realized that at the very least the Ochruhr king had to know that all of this was happening, and then he pieced together that several of the revolts had absolutely no hope if the Ochruhr knew about them ahead of time and were thus being set up to be crushed.
