I was looking through the Horizons lore and I noticed that there is very little on the Withered Aegis. Apparently, the Aegis was several factions of Undead whom Torrin Maclair united together to attack the Living Races. After Torrin Maclair's death (or assumed death) the Aegis broke up into different factions that are quite hostile to each other. That seems to be about all we know.
Some questions that come to mind are:
How many factions are there and what seperates them?
Which members of the Aegis are sentient? Is every bottom rung skeleton or zombie a sentient creature or are they merely killing machines? If the latter, is any part of the Aegis sentient?
Before the Undead were influenced by Torrin Maclair, were they aggressive and violent?
How did Torrin Maclair gain control of the Undead?
Since Torrin Maclair is no longer alive, what keeps the Aegis in the war?
Thank you.
