Knowing that you joined in a time before we had the fancy website, and fancier application sections, I do understand why you write an additional application for Kaèl, albeit that it is absolutely unnecessery, however I'll rate it just aswell, just know it's not part of the application for Thazad.
Let me begin with the following for other applicants: Never use smileys in your story.
Kaèl's story isn't fullproof, first part is that during the third war there were no Blood Elves, they weren't established as such until the near end of the greater "Third War", only until they neared the skirmishes with the Scourge and the banishing from the Alliance and the bonding with Illidan, they were named as such, they were warriors, knights or paladin.
Also note that Andorhal is the distribution center for trades (no wonder the plague was spread from there) and as such there is no specific "Ghostlands pass" to there, there are many roads.
Now about Thazad, there's two things I have problems with.
1: The competition between two cultists, Kel'thuzad and Thazad, seeing as the Cult of the Damned accepted every capable being, the Lich King wouldn't kill one of them over the other, at worst he'd sacrifice the lesser ones for greater purposes.
2: His interaction with Kel'thuzad, a majour lore character. I personally am against stories involving a greater lore character in this scale, for the reasons of working yourself into making up lore concerning that lore character too much, or because you make a mistake in your past concerning that character.
I'm sorry Kaèl, but for now I'd have to say no to Thazad, especially after your behaviour at a passed meeting which caused little confidence, I'll review it at another time and perhaps you can have a look at it yourself sometime and improve it.
