Actually the blue dragonflight is associated with ice and magic, so blue runes are quite alright there. And arcane (mostly in the warcraft universe) is purple.Quite Beautiful, however:
Blue is usually associated with ice. Silver or Gold is usually associated with the arcane.
My opinion though.
This is a great little model, but what I like most of all is that you strove to put some thought into an actual race design in order to inform your modeling (i.e. "what would the High Elven T3OD be?").
It's a tricky question; the T3OD can generally be seen as the "epitome" of the faction, but which "epitome" do you pick? Elves love magic, prize beauty, PRAISE THE SUN \|T|/, value wisdom & age... Bonus points if it's a flying unit (3/4 of them are). And there are loads of ways to fulfill that. I disagree with the Phoenix, but a "sun-bird" maybe... Alternatively some super-advanced sun-warrior...
But to give it thought, the High Elves entire raison d'être could be considered to be (Arcane) Magic; it's why they split off from the Night Elves in the first place, and what (fast-forwarding) causes their crippling downfall as a race in TFT. So a magically-focused, giant flyer... With loads of age/wisdom... Well, you couldn't do much worse than picking Blue Dragons. So kudos to you, man!
On to the building. Like I said, I like it. It's definitely patterned after the WoW Blue Dragon Nexus's's's's.... But it's still generic enough that it could go for almost anything Arcane & magical. In fact, I think it'd make a stellar "Arcane Waygate" or whatever; a series of tower-portals that connect Elven settlements.
Keep up these buildings, man. And let me know if you feel inspired to flesh out the Trolls, mon. ;P
Not if we're talking High Elves (which, as he stated, he is/was). They've never even heard of Outland; perhaps you are confusing this with a Blood Elf structure?A much better option could have been the Nether Dragons, creature wich they particularly have contact and friendship with in Outland.
