Hey! So this will be short. It's just the info in the pamphlet Hecate mentioned. Like I said last chapter, a lot of info is off the Harry Potter wiki page, so if your not very familiar to a lot of the terms, you'll want to read this. Oh, and when I use the term demigods, Grover is typically included.
Terminology:
Wizard- Humans with the ability to use magic
Pure-Blood- Witch or Wizard without muggles in their family tree
Half-Blood- A witch or wizard born to one magical parent and one muggle/muggle-born parent
Muggle Born- A witch or wizard born to two muggle parents. Pure-Bloods often refer to them ad Mud-bloods
Muggle- A non-magical human
Squib- A Half-Blood with no magical powers
Half-Breed- A human with one non human parent
To the Demigods:
There is a great deal of prejudiced against Half-Breeds, so you'll be passing yourselves off as Late-Blooming Half-Bloods
People Who Will Know of Your Purpose:
Proffesor Albus Dumbledore- Headmaster of Hogwarts School of Witchcraft and Wizardry
Madam Professor Minerva McGonagall- Head of Gryffindor House and Transfiguration Professor at Hogwarts School of Witchcraft and Wizardry
Arthur Weasley- Your host before you travel to Hogwarts
Molly Weasley- Your hostest before you travel to Hogwarts
Proffesor Rubeus Hagrid- Keepers of Keys and Grounds of Hogwarts School of Witchcraft and Wizardry; Proffesor of Care of Magical Creatures; Half-Giant
I know this is short, so... sorry. Next chapter, the demigods will meet with Hagrid to shop for their books and wands. And the in the chapter after, the demigods will arrive at The Weasley household. I know that in Order of the Phoenix that the Weasly Family is at Sirius' family house, but let's pretend that the kids were sent there for protection, and the parents stayed at the house. (YAY STORY CHANGES!)
