"Thank you both for coming, Mr. Manson and Ms. Wandsworth," Robert said. "Since time is of the essence I shall get to the point, if you don't mind, and as the others come I shall brief them. If they do not arrive shortly, I will meet you without them.
"Mr. Manson has managed to tame, or at least befriend 2 manticores. Not an easy task. And not predictable creatures either. They might be of some use to us. War has come to Hogwarts. It appears we have a dark wizard in our midst who may well be behind this making a bid for control of the wizarding world. In short, it is a name from your history books. Gellert Grindlewald has been resurrected via a horcrux and would very much like to own the world, it does appear. It may be that he has orchestrated this battle at the school. At any rate, because of the rising tensions in the school, I have put a couple of people I trust on school grounds without your knowledge--for their protection as well as yours.
"MIchael Tremaine is on the school grounds as it is. My daughter has gained entrance to the Forbidden Forest and she has been there for some time. She has taken control of the thestrals. She has also been camping near and neotiating with the centaurs to assist us, should we need it, in defending the school since our own numbers are a bit limited.
"As you know, Thestrals cannot be seen except by those who have already, themselves, seen death. That is one of the reasons I have sent Khaat. Her own experiences will enable her to see them, I believe, and I also believe that had she not, she'd have sent word to me.
"As for the centaurs, there are a limited number of them who will assist us. Their interests are purely their own. They do not want battle to expand into their homeland in the forest. Centaurs, while they are neutral, generally favor the 'white lighters', traditionally anyway, rather than dark magic. Your instructions are simple. You will find you will have little trouble gaining access onto the school grounds or into the forest since security at the school is already breeched. Go and help defend the school and protect the students. You may take a thestral and/or a centaur with you. They may be of some use to you. Khaat has both waiting for you in the forest itself. She has sent up a patronus from there, and will follow that by red sparks from her wand. Any questions?"
OOC: This is an intended part of the battle plot that you may indeed use. You may use a thestral to do some battle by air, if you choose. Or you can take a centaur with you. Both will be your own NPC's to control as you wish. Questions?
