Sure, we can think over the details about the Kingdom and the woods as we go. 

Well, I didn't get as far on the series as I thought when it first aired, taking a look back at the early promo clips for each episode. Only the first three episodes and a portion of the fourth seem familiar in any way. As for spoilers, don't worry too much. They don't really bother me unless it is some epic finale. Besides, if it isn't mentioned that the idea came from the actual series I would never know until I discovered the resemblance. If there happens to be an element from the show that would benefit the RP greatly, I'd say go for it.
