The concept of soap is first credited to the Aellenrhim elves, who are known to have been making cleansing materials early in the Age of Awakening. Animal fats were combined with alkaline salts and boiled in clay cylinders to produce a bar of soap like material that could be used for washing. However, many elven tribes have similar materials for cleanliness, for example the Ahrhim and Goltherrhim living in the shadow of the Argor and Hèckra volcanoes respectivey are known to make a thick, jelly-like cleaning fluid by mixing ashes and oil.
The reason the Aellenrhim are most normally associated with its invention is because it were these elves who brought it to humans, firstly in Voldar, but later all over Santharia.
There are many variations of soap. One noteable tribe of humans, the Trk'Matiu Kuglimz use tallow mixed with oil which they use to wash, but also, if left to tint their hair with. The most common soap making method is that now employed in Voldar, made from sea salts and fats and oils from animal or plant sources. The main sources of fats in modern Santharia are beef and mutton tallow; while palm and adlemir simn kernel oils are the principal oils used in soapmaking. Sahnrix sap and candlebush berries (if well diluted) can also be used. The raw materials may be pretreated to remove impurities and to achieve the color, odour and performance features desired in the finished bar.
Humans often scent their soap using herbal fragrances. Rose petals are a common scent in Northern Santharia, while icemilk and various fruits and berries can also be used.
