My game saw the Kurios wipe out the illians quite early(around t100). nothing i could do about it, as it took so long to march up with my troops. luckily the scenario isn´t lost at that point (the description isn´t very clear if the illians have to survive). But after this incident, the kuriotates rarely build a new unit, so my lucien(got crazed in a dungeon) plundered their improvements easily. After that, burning the illian cities was easy (one warrior each). Resistance was only noticeable from the bannor, but they were the first to taste my axes... The Grigory even attacked me with an adventurer( not upgraded!!), poor guy.
