[quote=""Olorin""]I was not aware of Dwarvish origins. I was thinking perhaps it had originally been a far-flung outpost of Gondor. I just checked both Robert Foster's "Complete Guide to Middle Earth" and the Encyclopedia of Arda website and neither of them mention anything about its pre-Sauron history, FWIW.![/quote]
I know I read it somewhere, but couldn't find it. All I could find is that Amon Lanc, before the coming of the Shadow, was Oropher's capital for the Woodland Elves before they fled further north into Mirkwood. I believe the dwarves were there prior to the elven settlement; as the seven houses of the dwarves spread out from Khazad-dum, one of them settled there for a time before moving on.
[quote=""Olorin""]They think the person Gandalf is fighting in Dol Guldur is Thrain, and I think they're right. His robe looks Dwarvish, and what you can see of the makeup appears Dwarvish.[/quote]
I too thought it looked like a dwarf, and the only one that could be there is Thrain. However, if he is fighting Gandalf, then that would be the first glaring departure from the texts that I will be very unhappy with.
Looks like PJ and Co. are trying to up the action ante once again by introducing a fight scene for added excitement in a situation where any knowledgeable Tolkien fan knows there was none. In fact, all of Gandalf's sojourns into Dol Guldur were successful precisely because he relied on stealth and secrecy, not going in guns blazing and making a ruckus.
Gandalf finds Thrain wasting away in a cell, read: IMPRISONED and HELPLESS, and moments away from death. Thrain is unable to tell Gandalf who he is or who captured him, but he does give him two vital objects: Thror's map, and the key to Erebor. It is from these two things that Gandalf is able to deduce the dwarf's identity and the importance of what he'd just been given. This becomes the impetus for the later quest involving Bilbo and the dwarves. In case anyone is wondering why Thrain was important enough to Sauron to be captured, it is because he was one of the wearers of the Seven Rings of the dwarves, which Sauron took from him upon his capture.
To have Thrain wandering around, obviously deranged and spoiling for a fight cheapens the dramatic and emotional value of the original scene and doesn't seem logical at all. Why would Thrain be on the loose inside an enemy stronghold? Does he attack Gandalf by mistake? Since he is supposed to die, does that mean Gandalf will kill him, or do orcs show up, drawn to the noise and then kill Thrain?
Whatever the answer to these questions, the whole thing seems forced and out of place already. Here's to hoping we are all incorrect about this very early assumption.
