Book Review (Theory of settlement)

Book - ERAGON
Author - Christopher Paolini

Eragon is a fantasy novel written by Christopher Paolini. It is the first book of the inheritance cycle.the book focuses on the protagonist Eragon who lives in a fictitious world called Alagaesia. The book has characters such as elves, dwarves, dragons, dragon riders, shades etc. the settling which captured me the most was the mountain city of dwarves, Tronjheim.the whole city is built by the dwarves and it shows theie mastery on stone.there are tunnels running through and through the mountain making passageways. Since the plot is centred on battle between the good and the evil, the architecture of the tronjheim is much more like a fort. The tunnels are broad but high only in the centre so that a person riding a horse can ride only in the centre and thus it slows down the attacks. The city is actually in the heart of the mountain and the rest of the mountain consists of flawless tunnels with the angles at the base of the wall are perfect right angles. Tronjheim is located inside a massive volcanic crater.a soft beam of light falls through the aperture, illuminating the craters centre. Since that is the only natural light available, the rest of the places are lit by thousands of lamps hung on the grand pillars in the tunnels. The ceiling is capped by a dawn-red star sapphire of monstrous size. The grandeur displayed in the mountain city shames anything every built by any other living being. The dwarves took this city as their home when they were forced underground by the evil immortal king Galbatorix and his dragon. The tunnels in the mountain were originally built to dig gold. The mountain city also houses Varden, the only resistance left in the whole of alagaesia. Nobody from outside world is allowed inside unless they know the entrance keywords which only a Varden can tell to another person. 
The imagination of the author and his concept of a mountain city should be lauded. I would love to visit such a place in my lifetime.
