Zurgo's
nature is done through the totalitarian nature of the Mardu. The primary focus to their activities and strategy is
, but because of
and
corrupting the faction, they have problems on a social level where they have a structure that only very ambitious people dare to challenge, and therefore the ambitious people keep the structure for that it secures their power. The only time that the Mardu as a whole rebel against this structure was when Zurgo, blinded by rage, forced his horde to do something it doesn't benefit off of doing nor wants to do. Thus, members of the horde rebelled, and Zurgo knows that his power is gone. It might be that if the timeline was allowed to exist longer and Zurgo was killed by Sarkhan, the Mardu might have seen the error in this way and changed their act.
In fact, it would be interesting to see Narset try and make an artificial plane from the old timeline as a science experiment.
The Sultai feel like a failure. I personally feel bad about them for reasons I won't disclose, but it feels like a mistake I made myself. Anyways, there's a huge difference in the Sultai's territory and Silumgar's. Silumgar destroyed all of the woodlands that surrounded the Sultai's territory, while the Sultai themselves never did such a thing, and in fact had several holy sites, such as Silumgar's skull. No, really. It would be sweet to see a human rise up in the ranks of the Sultai without the use of a rakshasa but instead through using their own unaugmented brain.
The Abzan's ambitious nature is weak. They have a predetermination complex with their form of necromancy raising the spirits of their ancestors. If an Abzan doesn't have an ancestor to commune with, that citizen would normally be at a disadvantage. Finally there's a person called Reyhan, which rebelled against the idea of surrendering to the dragons, and surrendering to someone petty enough to kill a group of people just because they commune with the dead. All things considered though, this faction failed to capture some of the colors because of the immense focus on
, and even splashed into
with Reyhan. All dark magic in the Abzan appear as undercurrents.
Narset herself doesn't capture the Jeskai's zealotry, but it may seem that she is pretty lax about making judgement on others. Or reading the laws of the Jeskai, because some of them are pretty stupidly designed. Anyways, while the Jeskai's internal structure is about accumulating knowledge, their foreign policy is militaristic. Take what happened to Tasigur for example. Narset probably didn't know what Tasigur is doing, or doesn't care.
Finally, the Temur, on losing to Atarka, lost their elementalist abilities. Information is also a major part of their society, and that was lost when Atarka came around. Their red element comes from their relationship with the Sultai. Many Temur were once slaves of sultai rule. Now, in the new timeline, they remain slaves. I would like to see some kind of rebellion against Atarka's hedonistic activities and anti-intellectualism.
