Please Critique my work II

Since the last one got ignored, i'll try again.

1. The Divine Three: Three elementary school kids (ages 9-12 and one a girl) of a place called Nexus City, USA, accidentally stumble upon a box with three strange items. After they learn of the magical powers that these items possess, the Oracle of Delphi takes upon herself to train them on how to us it. Now the three children must use their powers to defeat the evil Greek witch, Circe and her allies; Apep the serpent and Skadi, Goddess of Ice.

2. Secrets all around us: There are all sorts of creatures in the world. Some that people try to prove exist, others that some people only believe could exist. But there’s a reason why some creatures are considered fakes, they’re covering their own tracks. Bigfoot, dragons, ghosts, even aliens and all the other strange creatures from earth and beyond, belong to an organization called, The Secrecy. A group of creatures who have one thing in common, they seek protection from certain humans. But now the organization must deal with a former alien Secrecy operative who has seized control of a major human business empire and has schemes against The Secrecy.

You seem confused. The 'post your concept' thread can be found here: https://tvtropes.org/pmwiki/posts.php?discussion=12952425210A11943600&page=12#293

Well, it certainly looks like...a solid idea, I suppose. It's certainly one well refined by many writers over the years, so no worries there.

I don't really know what you want us to critique, a setting can only do so much, but execution can make it good or bad.
