From the introduction of Uttgart 1: The Ring of Gilrod:
Uttgart is a scarred and embattled world. It has been torn apart by inter-religious wars, natural cataclysm, magical strife, and inter-planal invasion. In many places the very surface of the land is blighted and marked by the passage of great forces. The history of the world as it is told around shielded fires at night is a sad and violent tale. For untold centuries Uttgart was a peaceful and orderly world divided into a large number of primarily maratime kingdoms. There were several major coastal cities, among them Lansnor, Ulkhar, Sardash, and Melitor. A notable inland city was Srotisal, the Citadel of the Five Races. At that time there were many races in the world. The two dominant religions were the Norse Pantheon, called the Cult of the Pool, and the Egyptian Pantheon, called the Cult of the Flame. Two other major religions were the assorted celtic pantheons, called The Cult of the Root, and a variant of the Greek Pantheon called The Cult of the Mists. Another significant, though not popular, faith was that of the Titan worshippers of the secret and exclusive Cult of the Vortex. Also popular were several other faiths which were new on the scene, most notably the Cult of the Eldar Gods, and the Cult of Chaos. It is in these religious rivalries that the conflicts which were to re-shape the world arose.
The Citadel of the Five Races is a centrally located hive-like city on the main continent of Uttgart. It is a paramount overland trading center, and is divided into five sections, each inhabited by representatives of the world's five major races. These races are Man, Saursens, a lizard-derived race, Night-Ghaunts, a race of winged-humanoids, Ocariths, a race of eight-limbed men, and the Alfkin, the conglomerate race of elvish kindred, including the Altalf, or high-elves, and the Dokalf, similar in some-ways to dwarves. It is in this citadel that the seeds of the conflict were sown.
Part of the citadel complex is a religious section representing the major faiths. This complex became very powerful and magically potent through the acquisition of artifacts and great knowledge. Eventually, the Shrine of the Sacred pool acted and began a policy of sending forth super-human representatives, as champions and missionaries, with the charge that they should spread the faith. In response to this the Temple of the Flame, long jealous of the Pool created a being for a somewhat similar purpose. After studying the situation they sent forth this being, a supremely skilled assassin, skilled in the use of both weapons and magic. His mission was to destroy the Pool and its followers, and his name was Gilrod.
Both major religions sent forth more agents, and the Root and Mist did so as well. However, none of these later creations were the equals of the first agents of the temples. Gilrod ranged far and wide through the world, expanding his power and the power of the Flame. He destroyed many Poolies, but his main foes, the original five Pool creations constantly evaded him. In time he grew great in knowledge, and became the first person to be initiated into more than one religion, when he was accepted as an initiate of the Vortex, and later of Chaos itself. The struggle continued between Gilrod and the Pool, as represented by the five champions, Thane Ormsson, Bjarki Grimhold, Silidur, Mirraraf, and Bjortak the Doomed. Eventually it entered a sort of a Cold War state as the antagonists settled down and established fortified places in far separated regions.
This state of uneasy peace lasted for a generation and a bit more. New, younger powers arose in the world, in the form of the mighty Druid-King Spielsatzenbrachen, a semi-human creature with a great power over the forces of nature, and Pwyll, King of Gwylleddare, a warrior of great renown. Unwittingly these two men, in league with Lord Xeron of Logrono, embarked on a fatal endeavor. They voyaged south in exploration, beyond Thulat, the farthest known island of the southern sea. There they found a strange land unknown to them, people by mythical beings. While exploring they encountered an unfamiliar being of great power. After a massive struggle they slew this being, only to find that they had killed the God Ra himself. As they looked up in shock the throne where the god had sat shimmered, and in it appeared Gilrod, who declared himself to be the new Lord of the Flame.
From this point disaster took the world as the rule of Gilrod widened. He entered an alliance with the Lords of Chaos, and from Castle Melanir he began to take control of the world. As the generations passed his power grew and his awesome nature became clear, for every few years he would enter seclusion, and emerge, not as one body, but split into two identical beings of equal power, psychically linked. In vain hope and blind terror the forces of light and good went into hiding, protecting themselves as well as they could, battle raged, whole cities were destroyed in an instant, and entire nations laid waste. Gilrod looked down on all of this and smiled.
it is 153 years since the death of Ra and the ascension of Gilrod. The Lord of the Dark Flame, as Gilrod is now called, rules a world at peace and enslaved, through minions like his lieutenant Lir, and in person, in his over 300 bodies. Order and direction have been established, and all is calm. Ageless and boundless, Gilrod seeks new endeavors and new worlds to conquer.
Uttgart is a setting used in several editions of Ysgarth. It is described as a "high entropy" setting to indicate the constantly-changing and chaotic nature of the campaign world. Information about Uttgart is found in the adventures included in Ysgarth Adventure Series (Uttgart).
Castle in the Void in Abyss (Issue 37 - Spring 1986) offers the following description: "Uttgart is a flat world, or to be more precise, it is a partial hemisphere with a gravitational source somewhere below the concave side and poeple living on the convex side. To all appearances for those living on the convex side it is a round world, until they reach the edge, which consists of a ring of bottomless cliffs and waterfalls which fall forever in space turning to vapor in the vacuum. Hanging in space beyond this limit are a series of small island segments which have broken away from the main body of the planet, many of them supporting atmosphere and life. This situation is maintained by the power of Lord Ourzon, though he has long been absent from the world and the magical power which keeps this situation stable is steadily deteriorating."
