I could or someone could say, "Hey Wurm, these new quests were added while you were gone...!" Since EQ2 doesn't say where they come from...
Sometimes EQ2U does explicitly say... when it's a drop. At least one is from an achievement, I think killing all the Heroic nameds. There's one you get via raiding. As for the others, dunno. Tell us when you find out.
I think you are looking for the 70 fervor blue adorn. It comes from killing all heroic named in CD. There is also one from finishing all the quests in CD.
The 55 Fervor rune is from killing all the names in Tier 1, Tier 2, and EH heroics. The 70 Fervor rune is from killing all the Tier 1 Raid names. There is another blue rune from completing all the quests in the Library and one more from the shiney collection in GUK Heroics. And of course the one you can get from the box - un-adorning the weapon.
