In lord of the rings, they seem to mine it. I'll give you a general overview: Mithril was a precious Silvery metal, very lightweight but capable of providing extreme strength in alloys, which was mined by the Dwarves in the deep mines of Khazad-dûm. The wizard Gandalf explained Mithril to the Company, when passing through the Mines of Moria: "The wealth of Moria was not in gold or jewels, the toys of the Dwarves; nor in iron, their servant.... Its worth was ten times that of gold, and now it is beyond price; for little is left above ground, and even the Orcs dare not delve here for it." "Mithril! All folk desired it. It could be beaten like copper, and polished like glass; and the Dwarves could make of it a metal, light and yet harder than tempered steel. Its beauty was like to that of common silver, but the beauty of Mithril did not tarnish or grow dim." Mithril in its pure form was apparently rather soft and malleable. It could be used for various alloys to produce extremely lightweight, hard and durable armour but it was also a component of ithildin. The Elves loved it for its beauty and presumably used it for jewelry and attire rather than weapons or armour. Mithril was extremely rare by the end of the Third Age, as it was found only in Khazad-dûm. Once the Balrog known as Durin's Bane destroyed the kingdom of the Dwarves at Khazad-dûm, Middle-earth's only source of new Mithril ore was cut off. Before Moria was abandoned by the Dwarves Mithril was worth ten times its own weight in gold. After the Dwarves abandoned Moria and production of new Mithril ore stopped entirely, it became priceless. The only way to obtain a Mithril-object at the end of the Third Age was to either use heirloom Mithril weapons and armour that were produced before the fall of Moria, or to melt down these existing weapons to forge new ones. The Ñoldor of Eregion made an alloy out of it called ithildin ("star moon"), which was used to decorate gateways and portals. It is visible only by starlight or moonlight. The West Gate of Moria bore inlaid ithildin designs and runes. While Moria is the only known source of mithril, there are inconclusive indications that it may also have been found in Númenor, the Lonely Mountain and Aman in smaller quantities. For the literal-minded reader, it is unclear whether or not Mithril is a real metal; many have thought it to be platinum, or iridium however, both are far too heavy to qualify as candidates. It is possible that this legendary material was modelled after titanium, as this metal, while actually quite abundant as ore, was very expensive to produce in its metallic form (especially by medieval technology), and has some of Mithril's properties of strength, bright silvery color, corrosion resistance, and light weight. Other possibilities are aluminium, or magnesium; these metals are even lighter than titanium, but not as strong or as silvery and shiny. (Famously, Napoleon III of France once bought dinnerware made out of aluminum because it was more expensive than gold at the time.) Certainly Tolkien, being highly educated, would have had knowledge of these three metals and the difficulty in preparing them. However, probably because nobody is known to have asked Tolkien about Mithril, it will never be known with certainty whether mithril is based on any real metal. The name Mithril came from two words in Sindarin—mith, meaning "grey", and ril meaning "glitter". Mithril was also called "true-silver" by Men or 'Moria-silver' while the Dwarves had their own, secret name for it. There's a short overview about what mithril is and stuff.. In LOTR.. TL;DR? Mine it, Buy a pick axe Find some mithril ore Mine it Get it Tell your alchemist how silly he is
Oh and Pi is very wrong, you can't get it from system wars, 'twas removed from KaW when people used to farm for mith by having one side smashing the other and so on.. That was called Mwars!
I forgot to add, without buying it you have to participate in EE wars, indi wars, round wars or primal wars. Indi wars for smaller or less experienced players are the best option to grey some experience and mith! Simply cast wave of conflict in the alchemist and you can sign up.. Go to clan events section and look at the war schedule to see what time is best for you! If you want to be in round or primal, try and find a clan that is willing to take you in and hopefully a clan that wins!
For a while there was speculation that the Devs would make Mithral available to be bought on occasion. However, as that would have the effect of allowing players a means of getting Mithral without playing the game as the Devs want - doing EE wars - it is unlikely this will occur again.
