Statuettes of dragons n stuff are kind of lame, no offence ppl
I would much more like something that looks really cool and "TESish" but still gives you something to use in the game. For example, I would love it if you got like a book, written in the language of the dragons, containing riddles and clues to things in game, like weapons, spells, power, houses and so on. So you have to translate it in order to figure out the location!
Also, a poster is never wrong, like a map or something
