So just to clear something up.
The most defining traits of each Greater Daemon are:
Bloodthirster: strongest daemons of them all physically.
Great Unclean Ones: Avatars of nurgle himself. Bloated with all diseases imaginable.
Lord of Change: receives visions of the future from Tzeentch himself
Keeper of Secrets: ????

I've always seen it as Bloodthirsters being able to run/fly straight at you and ruin your shit with an axe, Keepers of Secrets basically pacify their enemies into silent awe as they're cut apart. Much like comparing a Daemonette to a Bloodletter.

>Asks what a greater daemon represents
>Its named Keeper of Secrets
Makes you think...
>>54869927
>Keeper of Secrets
it's in the name: they are said to know every secret desire of mortals, and they use them to tease, lure and trap.
or maybe it's a joke about victoria secret, I never asked tho.

Lithe, agile, supernaturally fast.
Slaanesh and all his/her forces are for the most part the Snake from the Garden of Eden...
Remeber that and you never, ever be confused as to what Slaanesh represents.

Fastest/agile
>>54869927
Keepers of Secrets are what their names imply. There's one such story on one seducing an Eldar to get into her craftworld to fuck up an Avatar of Khaine. They're pretty much the snakes in eden, next to knowing tidbits of lore you won't find anywhere else, and are also gay space dancers.

What timeline is this again
>>54869927
I recall that in the older editions the artwork had it as marine sized and looked more like a minotaur

Greater demons have always varied in size in the artwork. From ogre sized pee wees to nearly Knight sized. It mostly depends on what the artist needs. Well that, and GWs new trend of making ginormohuge models.

If you are looking for some specific trait that is similar to the fluff that defines other daemons, "It is said that they can hear anything that is said anywhere, in any dimension, and it is this ability that earned them the moniker of 'Keeper of Secrets.'" At least I think that's what your looking for...?
