[b]Question #1[/b]:  I suspect that there would be noble Houses?  As in, people who own land and run services on them that benefit the kingdom, and would have commoners live on their lands?

I would say that is a safe assumption.  There would certainly be different noble houses in control of territories that pledge allegiance to certain lords.  There would certainly be a feudalism type government set up though of course most land would be under invaders control along with the commoners living there.

[b]Input #1[/b]:  I don't think I'd like to be an heir, as I'm very interested in playing a young knight with a low title who is seeking to redeem or restore her House's honor to its former glory, by striving to become a reliable leader and competent with blade & bow. But there's a twist, and here's a teaser: Her House's history isn't what she thinks it is.

If I get this RP up and running I would look forward to seeing what kind of character that turns out to be.

[b]Question #2[/b]:  Will this story focus on the results of large armies battling each other for control of territory, while our characters either float around it or perhaps dive straight through it?
[/quote]

I certainly expect large battles to be a part of the roleplay, though, especially at first, it will be more about finding backing, setting up cells in taken over territories to run interference and preparing for the battles to come, etc.  Small-scale at first but then ramping up whenever they decide to make a major move.

[b]Question #3[/b]:  Will there be any demonic or heavenly sources of magical power? Sounds like it is all self-energy based as it is. I'm just curious.

For the most part I'll keep magic a completely separate source from such influences.  In the case of blessings and curses, faith could perhaps be used sort of 'boost' but as a whole magic will not be influenced much by such sources.

[b]Question #4[/b]:  I think I noticed in your magic system draft a lack of magical traps?  Maybe it would be elements, but would mages be able to set, say, magical runes that react to certain environment conditions? IE: Someone enters this room and suddenly poisonous gas is conjured?

Magical traps could in fact be used and implemented but, they wouldn't last very long.  You wouldn't just be able to carve a rune and then leave it for a week to wait for an enemy, either someone would have to recharge it every few hours, or they would have to be set a short time before an enemy arrived.  Magical traps are possible but not very efficient and would require maintenance to make sure they had enough power to be of much use.
