Your better informed than I am about the reputations of Shas'O'R'myr and Shas'O'R'alia! I didn't know the characters had any reputation, though FW stuff in general has a reputation (hate it or love it).
I was just pointing out the fun FW had with R'myr's name. Back in the early days of WH40K there were a lot of puns, inside jokes, and even a little social satire in the "grim-dark future the 41st millennium". Sadly not so much anymore.
As to the fluff (wait for it....RANT ALERT! RANT ALERT! "Danger Will Robinson! Danger! Danger!"
Don't get me started on the confusing, contradictory and bizarre diversions into the ether that goes with the WH40K fluff! The Damocles Gulf is burning? Farsight and Shadowsun are (your choice): boyfriend and girlfriend, ex-boyfriend and ex-girlfriend, husband and wife [ta'lissera also translates as 'marriage']; Aun'Va was assassinated. The Ultramarine were BFF with the Tau Empire, but then are not? Or how about the classic: Blood Angels and Necrons double team the Tyranids?"Whoa there big fella!"
as Bob the Squat might say.
I love the 40K fluff and I like it when the fluff and the rules match-up; but it seems that most of the GW/FW folks either don't care, aren't interested; or too busy to come with anything fluffwise that is well reasoned, logical or even just plain consistent. IMHO it seems they are more interested in "pushing product", than expanding the WH40K universe. Black Library (except for Phil Kelly!) at least (most of the time) tries to create stories in the 40k universe that are a least believable.
Okay, so I don't want to hijack your thread into a discussion on the weirdness of WH40K fluff; but if anything is going to be done with either Shas'O'R'myr or Shas'O'R'alia, then I suggest that you will be the one to develop it further.
Nobody at FW or GW is going to do it! (But if they did do, it would probably be disappointing.)
DIY (Do-it-yourself) Aj'Tau!
1. Backstory: the Who, What, When and Where of Shas'O'R'ymr
2. Great achievements (earlier in his career, and then later on after the events listed in the FW fluff)
3. His School of War (Okay, don't know if the fluff already has this, but if not. Then why not invent his own unique school?)
4. How does O'R'myr fit into the great plan of the 3rd Sphere of Expansion?
5. Who are his greatest foes? Orks? Necrons? Space Marines?
6. Who is his Arch-nemesis (40K character), also who is his arch-nemesis within the Tau Empire? Aun'Va? Shadowsun? Kais?
Alright so you get the idea, if you want to see some more fluff on Shas'O'R'myr your going to have to do it yourself. There are a lot of writers here on the A.T.T. Orbital that can help you. We're all pretty friendly so just PM any of us and ask for a hand.
Really, I think we could a whole lot more HQ choices (and fluff options) than Aun'Va, Shadowsun, Aun'Shi and Farsight. Looking forward to seeing what you can come up with!
