The material known as Manyullyn in Tinkers' Construct borrows a word from a language called 'Lythian'. This language compresses words and concepts into one syllable so that each one is a complete thought and experience in its own right.

Below is its pronunciation and definitions.

Man'yullyn̄
Short Translation: Star Cutting Metal
Long Translation: An alloyed metal made of meteors that is capable of cutting anything.

Man - Star (No differentiation between the sun, meteorites, and other bright celestial objects)
▸/man/, pronounced like you expect

Yu: Metal, Object
▸/yo͞o/, sounds like "you"

L: Action, associated with motion
▸Adds an L sound

Lyn: Cut. Context dependent
▸/len/ Rhymes with fen and pin, sort of

Any material capable of splitting stars is considered Manyullyn. As long as it is sufficiently hard and can drive through a meteorite without fragmenting or deforming, the material is strong enough to hold its name. Most alloys that can hold this name are made out of a significant amount of cobalt and tend towards a deep purple sheen.

Crafting Recipe, Star Splitting Alloy

General Information for Divine Metals:
- Each hammer has a set of ingredients. Powdered metals and ores must be paired with a slime core of suitable size and an equal quantity of gray, untyped gelcast.
- Base materials are selected and arranged into sets. The pairs are important, as is the process for replication.
- Each hammer has one ore, one partially alloyed metal, and one pure metal that may have unusual properties

Required Ores:
- Charred Steel Powder, 1/10 quantity of other ores
- Bright blue Cobalt Ore, exactly half of which is metal
- Pure Silver

Other Required Materials:
- Three slime cores of 1/12 size as compared to a full quantity of ore. These colors must be bright green, dark green, and bright yellow. The cores must be overcharged with the purity of Life, an ode to the Realm, and the vigor of a Storm respectively.
- Gelcast of an equal quantity to the ores

Stage 1:
- The powdered materials must be mixed into the gelcast individually and crushed until the entire mass is uniform.
- Each of the three materials are layered on top of each other and laminated into sheets with a hammer of at least masterwork level. They are folded and laminated again. Fold twice.
- Each material has an interruption to this process somewhere. Details are listed for each one.

Stage 2:
- Each material has a unique method of transformation at this point. Details are listed for each one.

Stage 3:
- This is a finishing step. Any detailing or other shaping of the material must be done before the material hardens or otherwise solidifies
- The slime cores are used to "activate" the material and will be inert after the process is done.
- Materials will gain additional properties after they have been activated.


True Manyullyn - Star Cutting Metal
▸Stage 1: Grind up each slime core into a fine dust. After the sheet has been laminated, evenly spread out half of the dust on the sheet before folding. Repeat for the second fold.
▸Stage 2: The material must be rolled up and soaked in molten meteoric iron until it is soft and pliable. Work the material as if you were Hephaestus himself forging lightning for Zeus or a Master Slime-Crafter. If the material becomes too hard to work, simply soak it again in meteoric iron.
▸Stage 3: Finish the material with the Tinkers' Worksong. All that is required is an earnest effort to ignite the spark in the material.

Additional Properties:
▸Cutting tools become unnaturally efficient at slicing through anything that would resemble a "star". This includes meteorites, comet debris, celestial creatures, or anything that has launched itself to space and fell back to earth.
▸Hammers or other blunt tools have a similar effect, but tend to bend the material as if it was malleable
▸Sharp tools such as arrows tend towards pulverizing the material into dust as it makes a hole through the object it strikes
▸Any object made out of Manyullyn is supernaturally tough and resistant to all kinds of damage.

Excerpt from a Great Work
Upon completion, each hammer was evaluated and graded. The additional properties were tested and verified separately. Results below.

Description
▸A standard blacksmithing hammer without any frills. The hammer is constructed in one piece. Leather is wrapped around the handle for comfort.

Material
▸An unusual alloy made of steel, cobalt, and silver named Manyullyn.

Finish
▸Purple, matte, smooth.

Quality
▸Magnificent

Notes:
▸Despite being in the shape of a hammer, the tool is capable of splitting iron from a fallen star as if the star was wood and the hammer was a hot oiled knife.
▸The hammer is impossible to scratch using standard tools. It is heavy, unreasonably so.
▸A small mark of a hammer with a blade for a handle is inscribed on the bottom of the handle.
