Annbild Hrolmir, or Annbild's Entrail is a great lava river that courses across several regions of Brucrumus's Underdark. It was named after a legendary captain of the guard that served under Surtur in the Creation War. Surtur honored the death of this hero by naming one of the Great Vein's rivulets after him.
Annbild Hrolmir is a great river of lava that though immense in length is but an artery of the Great Vein of Surtur. The Annbild Hrolmir artery is fed with lava from the deepest reaches of the Underdark. Starting from the Great Vein, lava pushes straight up for many leagues through the Sygning Spigot and then levels off at where it then becomes the eastward flowing magma river Annbild Hrolmir.
When pressure is great, eruptions occur at various points along the river. The pressure releases are active volcanoes, while in areas of a dead volcano the area has undergone such changes that pressure is no longer channeled into the volcano. Annbild Hrolmir begins in sector Sygning of the Underdark region Phangul. It flows eastward with the first pressure release being the volcano Traeulf. After this volcano the lava river continues east for another four hundred miles where it splits off into two. It goes southeast into Ufthag and continues eastward across the bottom of Garathral. The split lava rivers feed all the volcanic activity of Agulbandal, and its four active volcanoes - Vaermund, Kradlod, Vistlod, and Trylming. Leaving Garathral, the lava river continues east, releasing gas and smoke up the Annbild Pipe and then cutting south where it feeds the lava tubes of Bolmod. In Yol Skerah, a region beneath the Aerie of Dragons, the lava river splits into three with each river ending at a volcano.
Annbild Hrolmir can be travelled by lava barge. It is not a normal route for most though because few can handle the often noxious and poisonous conditions, and extreme heat. The people of Surticon are the river's major traffickers. They use it move goods to distant ports from Sygning to Yol Skerah. Travel along the lava flow is stopped in areas where the lava completely fills the tubes. In these areas, a land journey is undertaken to move to the next open area where more lava barges are staged. Beyond the environmental hazard of the river, there are also bands of salamanders, fire snakes, and other fiery brutes.
The lava barges of Annbild Hrolmir, with their crews of fire giants, are the best protection against a hungry fire snake or salamander wielding a man-catcher.
