When the primordials were defeated in the Creation War, some of those captured were imprisoned on the worlds of the mortals. This was necessary because moving them across systems was just too expensive and time-consuming for the Nawirrûs Covenant; especially when they were now facing another threat from the demons in what became known as the Demon Spawn War. In the Horgon Era, a primordial engineer named Devgwer escaped his vault on Gatheghu. He was bound to the land with angelic runes so that he could not leave, so he devised a scheme to stay with the land while cutting it free of the continent. He put 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 on storm giants, paying them with angelic and primordial spoils hidden away and left behind from the Creation War. The storm giant workers were put to work with Mauls of the Titan (primordial relics first created in the Creation War). These magical hammers were used to shatter an ice seam that stretched for three hundred miles. It was not necessary to shatter all of the ice, only 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, the Ark of Devgwer, eastward into Nielalroch's powerful ocean currents and waves. The gap in Vhurghad's coastline became known as the Devgwer Rip. As the Ark of Devgwer moved across the ocean, parts of it broke free leaving a string islands that stretch 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. This created an uprising of the land that is now called the Devgwer Humps. Devgwer was not the only thing riding on this short-lived island. On an island of nearly 10,000 square miles, thousands of dinosaurs were brought to the shores of Brucrumus with the Devgwer Humps and the Tiyalashe plains becoming their new abodes, and hunting grounds.
Varous holds of the Tarag-Khâlu Enclave employ dinosaurs as pack animals and steeds. Some even use raptors and like meat-eaters but this practice is rare. It comes with costly upkeep with the beast's high meat requirements and dangers of predatory instinct like when the mount turns on the rider to sate its hunger.
