Kaldsfang is the I.C.E. Age term for what is now called the Trollfang mountains and forest for the modern history of Elanthia. While it is called "Kaldsfang" in the Quellbourne source book for Shadow World, and so by the people of Kelfour's Landing, in Saralis it is called the "Saral March" and in the Rhaya tongue of Jaiman it is known as the "Dragonsfang." In spite of ultimately meaning the same thing in different languages, the term Kaldsfang was converted to "Trollfang", while the forests and street labeled Dragonsfang became "Dragonsclaw". The unaltered phrase dragonsfang is still referenced near Glatoph.
There seems to be nothing implying "kalds" meant troll. In the Quellbourne source book the Dragonsfang are a subset of the Kaldsfang Mountains. They are the western four mountains near Claedesbrim Bay, which is now called Darkstone Bay. These are Rihtoth, Smatoth, Weytoth, and Lyftoth. They are roughly two to three miles in height. The outer mountains of Rihtoth and Lyftoth are taller than the inner mountains of Smatoth and Weytoth. Smatoth is now Sentoph, and Lyftoth is now Zeltoph. Wehntoph corresponds to the position of Rihtoth, and there is no mountain in the position of Weytoth.
The Kaldsfang Mountains exist partly in the game, but seemingly or not obviously all of them. The originals were all Seoltang. There are some that were given new names but were disregarded, while others do not seem to be on any known list. It is theoretically possible these words are still referenced somewhere, if not in the room descriptions then perhaps objects, even items in lockers or inactive accounts. In the maps of both the modern game and the I.C.E. source books there might easily be small mountains in the range that do not have established names. These were the major named mountains.
|I.C.E. Name||Seoltang||De-I.C.E.'d Name||Exists?||Modern Analog|
|Rihtoth||"upright" + "mountain"||None?||Maybe||Wehntoph|
|Smatoth||"small" + "mountain"||Sentoph||Yes||Sentoph|
|Weytoth||"road/path" + "mountain"||None||No||None|
|Lyftoth||??? + "mountain"||Zeltoph||Yes||Zeltoph|
|Rototh||"red/copper" + "mountain"||None?||Maybe||Thanatoph (peak 1)|
|Hetoth||"high/tall" + "mountain"||Zeltoph||Maybe||Thanatoph (peak 2)|
|Blototh||"blown" + "mountain"||Glatoph||Yes||Glatoph|
|Straketoth||"strike/ore-vein" + "mountain"||None (*)||No||None|
|Galtoth||"poison/bitter" + "mountain"||Keltoph||No||None|
|Feortoth||"far/isolated/fear" + "mountain"||Startoph||No||None|
(*) In theory "straketoth" would be "straektoph", as "strake" terms were listed as "straek." Lyftoth and Hetoth were inconsistently changed.
Straektoph, Keltoph, and Startoph would theoretically be on the north side of Darkstone Bay, in the Seolfar Strake (Modern: Lysierian Hills) region past the part of the map we can visit. This would be the peninsula still represented on the maps without any detail. However, the island with Feortoth (Startoph) is no longer present, which is where the Shaaljin (Modern: Zhaolmin) monks primarily resided.
Behind the Scenes
In the later Shadow World lore for the Xa-ar peninsula there is mention that some parts of the Kaldsfang mountains reach down into the demonic Ash Lairs. In the Quellbourne book from 1989 the gnoll lair of Stonehold (Modern: Cavernhold) is near Hetoth, not Lyftoth. The foothills of Upper Trollfang shows Zeltoph to the south, but then by Cavernhold says "you have made your way far to the east and are now directly south of Zeltoph Mountain." This may be internally inconsistent, and is inconsistent with the source material. It might be Lyftoth and Hetoth both being turned into Zeltoph. Neither are on lists.
