Many will argue that Rune Magic is the same as modern-day engineering.
Of course, they both involve creating something from complex calculations and symbols. However, runes aren't just symbols; they are like alphabets that, when put together, can create something meaningful.
You can put rune symbols together to form teleportation gates.
You can also create barriers, weapons, healing arrays, and even use them to build structures (machines) that can think for themselves.
The possibilities are endless.
It all depends on the rune master's skill and understanding of the runes they use. Aside from the understanding, the application also has a part to play.
Knowing how best to put the runes together can go a long way.
Each rune has a meaning. Just like every alphabet, mathematical symbol, and computer code has a meaning, runes carry the same feel and meaning.
Some are similar in a way, while some are completely different.
