I tried all the LoL wikis that I could google and Im still not sure what is hextech. I think its a company that makes and/or finds weapons and other gear but please correct me if I am wrong.

While I do not know for certain, I get the feeling it is sort of.. a craft which mixes magic (Hence the Hex part) and technology (Obviously Tech, ergo; Hextech?).

Seems to be implied by the 'hextech' items, obviously the Hextech Gunblade is a gun, which is technology, though numerous items its made from are quite magicy, and there are the glowing runes along it if I remember correctly, denoting the magic.

All just a presumption on my part. One thing is blatant though, that it is heavily Steampunk influenced, just modified to fit a bit more smoothly into the setting, which is fine by me.

It is like Magitech is in Dungeons and dragons, its mechanical/steampunkish devices with magical augmentations.

Hextech is basically Runterra Steampunk from what I've seen...

I love Hextech. I'd like to see a Hextech skin available for every champion. Consider it sold.

Thank you all for the information ^-^

Short Answer:
Hextech is a slang term for techmaturgy. Think of it as technology fueled by magic. (As opposed to steampunk, which is technology fueled by/based on steam power.)
