The death of the Slann would definitely be a shock, but don’t forget that for the highest of Slann, death isn’t the end, as is the case of lord Kroak, if the skinks ascend to leadership options, it would open more flexibility into our armies from a gameplay standpoint as well. The Slann dying off adds something our army didn’t quite have much of before, and that is a more inner struggle beyond the struggle against chaos and the great plan, if you look at it from the perspective of the Seraphon, these times are uncertain and they have taken drastic measures without knowledge of what to do next or what will happen, using the example of the recent story, Maq’uat is sad and afraid when he realizes his master won’t be waking up ever again, as it seems he is barely alive and dying in his sleep, instead of panicking however, Maq’uat knows that he is the next in the chain of command, and takes action for what he sees as the right thing to do for the sake of their future. I’m sure this can be interpreted to mirror our own situation somehow, but then we get back to how this relates to this thread, the new spawning.
With the new spawning, we learn a lot of interesting things that could foreshadow our army’s Future. We know that the new lizards are ‘born with hate’ and will be suffering side effects of essentially bursts of feral aggression as a result of being improperly spawned. If we get new units. I feel this will be the route taken. The summoning mechanic could be added to some sort of new unit representing the spawning pool activation, or changed some other way. From a story standpoint the very idea of this imperfect spawning is fascinating, as we don’t know how the newborn savages will react to such an unstable time for the race.
