Here's how they extract clathrate

There's more than just pillars, coal, gas, and oil off the northern shores of Attland. King Yarl had banked on the seafloor to have more than scientifically discovered amounts of clathrate. King Yarl was the first one to discover and confirm that clathrates under seaflor do contain hydrocarbons, and off Attland's shores, they contain propanes, butanes, pentanes, hexanes and sometimes higher hydrocarbon alkanes.
The Oilbelt Corporation's platform looks like it is an oil drilling type, but it is actually a clathrate extraction platform (note the absence of the rig.) Clathrate is heated and processed to separate hydrocarbons, which are concentrated and stored to be offloaded into the company service tankers.

A peek at the Chasm's natural arches

Most of the upper reaches of Yahalma and Glada rivers have naturally and mysteriously formed ledges and arches. This is a series of arches that have been finished as convenient bridges in the lower Chasm, over the Glada River.

Shortage of high-end diamonds causes Koborg to up the gold price

Shortage of high-end diamonds causes the Queen to up the gold price, and very wisely, thus increasing gold purchases which initiated chain reaction of upping the gold prices worldwide.

Koborg Bank and its Corporation, owned by the Queen, has been adhering to a specific formula for gold management where most (unspecified) of its gold is purchased with cut diamonds of more than 1 carat in weight, whereas most of the gold acquired for the Attland's national government is purchased with preferential barter privileges from Attland's gold producers. See gold prices in the Reference section on top right.

Giant vine trees serve as village cores

Attland's jungle is the northernmost of world's jungles, being on the same latitude with South Carolina. Due to the Northern Mountains drawing down cool rainstorm weather, which mixes with the warm, moist Gulf Stream air, creates unusual cases of wet rain shadows both north and south of the mountains.

The misty forests are home to Attland's indigenous trees, such as the vine tree (no connection to grapes). The tree is capable of reaching 100-200 meter in height in over 1000 years of growth, and be about 20 meter in diameter at its base, such as the famous Great Tree of the Tree Village, in the bottom picture. This tree is over 1800 years old. The nearby trees are about 1000 years old.

The trees in the first picture are about 100-200 years old, growing along Yahalma River.

How Treasures from Europe made their way to the island

These treasures are the reason there is still a heavy flow of European tourists coming to see or pay tribute:

Excalibur

Zulfikar, or Dhu L-fiqar

Falias, the coronation stone captured from Fál (Lia Fáil) or from the Hill of Tara in County Meath, attributed to wizard poet Morfesa or Fessus.

Gorias, the spear (sleg) of Lug, attributed to wizard poet Esras.

Findias, from wizard poet Wiscias sword (claideb) which belonged to Núadu No one ever escaped from it once it was drawn from its sheath, and no one could resist it.

Muirias or Murias, from wizard poet Semias, the communal cauldron (coire) captured from the Dagda

Paradise Falls of Emerald Valley

This is Paradise Falls of the northern Emerald Valley, on the Yahalma river, where the Braided Rivers region starts (see the Valley Gates, and here and here ).

The Horns of the Emerald Valley

This is a painting of a puzzling rock formation protruding out of nowhere in the middle of the Emerald Valley. The Horns (and The Pillar Pile, in the background) are not sedimentary rock, nor do they have signs of erosion by wind or water. Maybe they were eroded long time before geologists think, and the landscape around them is a lot younger, making the Horns look out of place.

Another view of Marlboro at night

Here is another night view of Marlborough's Zion Island (closer than the view here) The giant bridges are better defined by their lights, rather than during the day by sun, which cannot describe the bridges' life.

A fjord that is a river

This fjord is long and very narrow, so typical of the island's fjords. This one is less than 1000 feet (330 meters) long, and no more than 70 feet wide, terminating in the typical, wide bay about 130 feet in diameter. It is locked between 1000-1400 foot high cliffs. The most interesting feature is the around-the-clock tidal flows that make the fjord into a river of reversing flows.
