As I remember it, isn't Ayem supposed to be the most popular and loved of all the Tribunal?
It's been a while since I played the Tribunal quests, but I certainly don't remember any major grumblings from anyone.
People always seem to assume that bonkers, bereft 'Lexie post Heart destructon is representative of the rest of her entire life. She was the Mother of Mercy, wandering the streets, helping the sick and poor, smiting the evil. In no way did she struggle to maintain the love of the people - it was as strong, if not stronger, for her than any of the other Tribunes.
Unless I'm forgetting key speech from Tribunal, of course, where everyone confesses to hating Almalexia. :shrug:
Morrowind the game is just highly focused on Vivec, so we don't really get to know much about the other two kids.
Muthsera,
Although it is true that Almalexia was the "most popular" of the Tribunal deities, she needed that faith and adoration of her people to bolster her strength. Faith conveys strength to gods irregardless of whether they are gods ab initio, ascendant or apotheotically larcenous (as were the Tribunal).
"It has been theorized that gods do in fact gain strength from such things as worship through praise, sacrifice and deed. It may even be theorized that the number of worshippers a given Deity has may reflect on His overall position among the other Gods." (http://www.imperial-library.info/mwbooks/overviewgods.shtml)
Her need for her people's faith is shown when she said
"Your death will end this prophecy and unite my people again under one god, one faith, one rule by my divine law." to the Nerevarine right before their final and fatal last battle.
Additionally, her divinity originated from the same source as did Vivec's, and Vivec demonstrated his need for his people's faith when he responded to the Nerevarine's query regarding why he made war on the Nerevarines and why he suppressed the Apographa:
"Why did I try to kill you? Because you threatened the faith of my followers, and I needed their faith to hold back the darkness. ... Why did I suppress the Apographa? Because it was such an unfortunate mixture of truth, falsehood, and speculation that I couldn't afford to manage the confused reaction of our faithful. Any doubt whatsoever weakened their faith, and we needed their faith to give us the power to maintain the Ghostfence."I believe that we can clearly state that the Tribunal drew power from their followers' belief, love and faith.
Yours in the Scrolls,
