Zakaht, eldest brother of the alicorns Celestia and Luna.
Zakaht is the god alicorn of invention. He is a tall, rather thin, jet black stallion with a silver/gray mane and tale. He ( compared to celestia ) has a pair of large wings of which some of its bones are on the exterior of the wing. Despite this, he still flies as well as any other pegasus. His horn is isn't as long as his younger sister, but that doesn't hinder his "magical awesome-ness" in the slightest.
His cutie mark is a white skull inside a nine-headed gear. Symbolizing his powerful, but dangerous magic.
Being the god alicorn of invention, he can use Crislan magic. Crislan magic is a magic invented by him, which allows him to use materials around him ( be they raw or refined ) and refine and reshape them into anything.
Crislan magic can also be used by any kind of pony, as long as they were born in Ethorea. But that doesn't mean anypony can turn a small pile of iron into a giant mechanical construct, one can only reshape materials into something of proportionate size.
But with a magical gem called "The Faust gem" Zakaht can ignore any rule set by the magic. It is the only one of the kind and cannot be recreated without a nation's worth of stupidly powerful unicorns, thankfully he is brother to a pair of alicorns with powers of other worldly proportions.
