Late in the Horgon Era, a Thrallrir engineer named Devgwer psionically shattered the chains that had bound him for more than six thousand years. During the Dawn Era, Devgwer served as chief engineer under Cari'phis for all construction efforts across Malurn and Vhurghad. In 1841 HE, he broke his chains, but Devgwer was not free. When he was captured and bound, Nawirrûs jailers had also placed powerful magic to restrict his movement. These angelic imprisoning runes, inscribed from the fingers of one hand, up the arm, across the back, and down the other arm, made it impossible for him to leave sector Gatheghu. This was a secondary measure put in place after his capture by Nawirrus forces. Devgwer was intent on leaving Gatheghu, correctly believing that it was only a matter of time until word of his escape spread. He gathered items stashed away since the Creation War and undertook an engineering plan of such grandeur that it could not have been pulled off when the angels were present. Devgwer placed Cari'phis Icicles, powerful magical devices used to convert rock, sand, and earth to ice, across the northeastern part of Vhurghad. When these were activated, they turned the ground into a deep seam of ice forming a great half-circle all the way to the coasts. He then hired storm giants, paying them with angelic and primordial spoils from the Creation War. These storm giant workers were equipped with great pile-driving hammers called Mauls of the Titan (primordial relics first created in the Creation War) and tasked with shattering the ice seam that stretched for three hundred miles. It was not necessary to break all the ice, only to crack it enough for it to weaken under pressure and heat. Two months later, part of Vhurghad's landmass broke free of the continent and began drifting out to sea. Devgwer rode this newly created island, later known as the Ark of Devgwer, eastward into Nielalroch's powerful ocean currents and waves. As it moved across the ocean, parts of the island broke free, leaving a string of islands stretching from the Devgwer Rip to the mouth of Tarag-Khâlu. When the remaining Ark of Devgwer reached the continent Brucrumus, it smashed into sector Ara'phis of the Troll Bogs, creating an upheaval of the land known as the Devgwer Humps. Thousands of dinosaurs had been brought along on this short-lived island, and today the Tiyalashe plains are a haven for these creatures in such numbers that pockets of civilization on its fringes build great walled fortifications and patrol their frontiers on the backs of triceratops and other great beasts. Agents of Ishtu Irrai were present when the Ark of Devgwer merged with Brucrumus, but their search for Devgwer proved fruitless, hinting that he may have been devoured by a dinosaur.
The rugged Devgwer Rip encompasses a dramatic landscape, transitioning from sandy coastlines to towering 600-foot cliffs. This peculiar region appears to have been violently torn from the surrounding terrain. Tunnels within the cliffs grant access to the Underark, the subterranean domain beneath Vhurghad. When Devgwer sundered an island from the mainland, the denizens of these caves and tunnels retreated deeper into the Underdark. Since that time, these locations have become the aeries of pterosaurs and other avian creatures.
