Psionics, Elementalism, and Summoning

Their main strength is through summoning and working with Azerai / Ziggurani in addition to psionics, being a Gem Dragonborn clan and all. Their mental control and connections, and this ability to connect multiple people extends to elements too. They are the only ones who could animate dragonbreath and fuse paraelemental anything. 

Their partying was renown due to their unique powers, as through pure psionics Eshire could orchestrate the firepower of blue and redscales to produce fireworks all by design in addition to elementally-infused clothing. 

 It is possible for other-colored Dragonborn to become psionically gifted, with enough exposure - but the same cannot be said for other races. 

Housing

The greatest amalgamations of different building practices, taking in all techniques an styles. 

Before the destruction of their territory, they had Lavalamp Beetles made of earth and fire to work as streetlamps. Their trees have leafs of literal condensed wind and water, enabling somebody to pluck one and have a rainstorm in their pocket. The clan had Mud Mole Azerai / Ziggurani that kept the roadways flood-free and maintained farms at the perfect situation for growth. 

Multicultural Alliancing 

Any clan in alliance with Eshire gives Eshire members the ability to operate by the allianced clan's customs and values as if they're a member of that clan.

Ideology

They usually accept other-colored scales if their mental and/or physical ideologies align - in which they usually take tattoos in the corresponding color.

Arts & Crafts

Their bestseller is in the arts.

 Eshire culture utilizes artistic mediums and a new unique one of ANIMATION! Eshire can use diamond and other gemstone materials to lay out illusory fields. Once you step over diamond dust threshold, you're taken and see a mirage of city streets, an entirely different nation.

They are even able to create tools, for activities such as bike-riding, that enable users to use the bike with their mind instead of their legs. 

Seven story building. Aztec inspired inside. Stonework murals.

1. On ground of first floor, the ridges on inside can make it so that perhaps more of these floors or on the first floor, we can see that it leaves room for modular wall placement? We can build out a maze in here if we like, but it seems the first floor is built more practically with dividing sectors for the various maintenance needs and.. divisions of labor that the Ershire clan utilizes. There is a mazelike exit into a separate room looking like mage's quarters. It's got a globe resting inside, different vials, corkboard - as it appears to be a planning room. 
2. With the wave of a hand, Myrmetok is able to make the room go brighter and windows change color. 
   

Once upon a time their leader, Krulrac, himself is a silver-scale but found his own reasons to pull together the lost & misplaced dragonborns and other races to create one melting pot clan that can accept those that don't make it too far in the other dragon clans.

Crops

Mirror Motion Plants

Flowers that react/display emotions of passerbys. Starmoles are monsters that eat these flowers, considered an invasive pest. They tend to be afflicted by the emotions of the plants.
