1) -Look under the Character Development forums, right around the same area you submit characters. You'll find a host of development threads others have written, also commmonly known as journals.
2) McCloud is not the most unique name in the world, despite it being the last name of one of the Highlander characters. However, I'll leave the answer to this question to a DM.
3) I'll let a DM, perferably Ed handle this one and the next one.
4) see #3 (as far as I know, Ed and L are open to new ideas and lore)
5) If it's not in the handbook, PM Ed or L and ask what they have to offer about the places, or hop onto IRC and have a chat with the DMs there.
6) Yes and yes.
7) Magic can do anything, but I'd likely think that the spell would work in causing the character to become amnesiatic, forgetting everything from his/her past, not just combat training, except for maybe hints from objects and the like, so the character slowly gains his/her memory and skills back as they discover more of themselves. It's not a new idea really. This, of course, would have to be approved by the DMs. As for names, it really doesn't matter what the name is as long as the effects of it are described.
8)No, there isn't a base spell whose main purpose is to cause amnesia, of any sort. A strong enough mage-type could produce the effect, however, basically creating some sort of arch-villian or unknown figure in the background of your character. Naturally, if approved, the figure would have to be an NPC, and could make for an interesting CDQ later in your character's life should he have to face down the one who stripped his/her memories away.
all these answers are my opinions and theories based on my current knowledge of and experience within Layonara. everything I suggested is subject to DM review.
