Attitude
Militaristic, disciplined, emotionally-stifled.
Housing
Whilst keeping things more simplistic, they are grandmasters of pottery & clay masonry - able to build sturdy and intricately designed multi-leveled stone houses out of seemingly any rock they come across using their high degree of fire control. They are able to act as walking kilns capable of melting all sorts of clay, brick, sandstone, and cobblestone into VERY well sought after glass products. Much of their buildings intrinsically use sands & glass in their designs, leading to SOME dwellings that can camoflauge during the day but at specific points where the sun hits it, the houses in SOME grouping reflect some near-magical refractory shows causing lights to dance about as if the light had a will of its own creating spectacles on the daily that even for these brutish people they can take a moment to admire their grand designs. They utilize stained glass expertly to portray their history, morals, and even rules.
Favored Weaponry
They prefer slashing weaponry they can use with strength, or some subtle dexterity but mainly strength.
Geography
Valleys, jutting plateaus and sires - much has been dug out and artificially moved, it's similar to observing an earthbender has been here. Challenging to find, not huts dug into the earth but some wooden and stone huts built onto the sides of these spires. Even blackrot iron towers peaking up past, as its very, very noticeable here its much dimmer; pronounced, this haze hanging about the city - but now here, it looks like JUST above the blue dragon statue, crackling with electricity, just above is an everpresent almost on the cusp thunderstorm that seems ALMOST ready to unleash a fury.
Sometimes, some ACTUAL lightning strikes, cracking down hitting many of these...Spark phrax..? But the steely-blue hues are different, might be something else or it might not... but these great crystalline oblong crystals are everywhere - especially around the fortress. We see it almost creates not a tesla coil, but a fairday cage of near-present ionic energy making an inherent trap that unfortunately, one dumb bird is unwise enough to fly near-enough to see a CRACKLING LIGHTNING come and BARBECUE IT right in the sky.
"The BLUE DRAGONBORN are responsible for the haze, said some crap in the meeting about forego exposition to counteract the Azerai and growing threats of the Wildfires" -Crazhdor.
As our lot travels through, nestled hidden amongst mountains and trees there's multiple training areas, the square is actually hidden - having multiple semi-hidden entrances leading underneath the actual fortress leading to heavily guarded cave systems containing various phraxstone lanterns keeping the place cool, well-lit, very nicely aereated. Even some of the marketeers and merchants lower their voices as outsiders near.
Sharendi
A tradition for dueling that may be challenged to Dragonborn, even children as Terestria demonstrated against Phesier Jorin 29the of 1097.
