Wow, that's a lot to answer, lol.  Let's start with the Norwegian names first.  Some of the names are Norwegian, some are Sweedish, some are Bulgarian or even Russian.  I took names from many countries that I believe would attend Durmstrang.  Russian and Bulgarian mainly because of Viktor Krum, who was a Bulgarian Seeker, and Sweedish because Sweeden and Norway sit next to each other, just as Scottland and England sit next to each other and students and staff from both as well as Ireland are all mixed together at Hogwarts.  The names I did choose were chosen because of their ease to say and remember by readers.

As far as the culture of Norway, I have researched it as well as Sweedish culture, and plan on having a mix of both.  I have never been to either one and don't pretend to be an expert on either, so what comes into my story will be from my research online.  Some of this will be explained in the story of course in later chapters as Harry and Draco ask questions and seek answers about this strange new culture that they've entered.

As for Printzhof, I chose a fake name (Yes Sweedish) because I can't see Durmstrang sitting beside a well known city or town in Norway, just as JK Rowling chose to make up Hogsmeade instead of sitting Hogwarts outside of London or some other known city.

As for Severus being Christian: Christians are human beings and like all people, religious or not, have faults and do not always follow the word of God.  I know many Christians who have a hard time forgiving, or who can be just as vindictive and unpleasant as some of the athiests I know (some of both in my family included).  Part of being Christian means admitting that you're human and that you can't ever be perfect and need God's help to get to Heaven because you haven't a hope to get there on your own.  I wasn't planning on making religion a vital part of the story, but I had had a request to include a scripture in the story (at which point I was going to do so as a quote at the beginning of a chapter).  I'm sorry if you feel the need to stop reading because of Severus' Christianity, even though it has really not been mentioned too much in the story up to this point,  but I often see other stories here at P&S and other HP fansites encorporating pagan and other religions into their stories as a part of their characters thoughts and feelings, and I see no wrong in doing so here with Christianity.

Just one more thought before I leave off here.  I have had some grevious slights done against me and they have hurt terribly, but I have truly found that forgiving and then forgetting (in other words not thinking about them, not bringing it up, and not remembering) has not hurt me in any way, and has lifted burdens off of my shoulders.  I grew up Athiest and grew up carrying around the hurt of past offenses and not forgiving people, and am determined now not to live that way any longer because I know what it feels like to be able to let go of something now.  I think that's something Harry knows and wants to feel.  He doesn't want to continue walking around feeling old hurts from the Dursleys or his friends.  He knows how Ron is, and accepting his friendship once again is not forgetting how Ron is, just acknowledging that he is that way and accepting it.

Thank you for your review, it gives some good insight.  Constructive criticism is always welcome.
