Beholders, I don't care for so much. They don't make a lot of sense to me. Where do they come from? What do they want? I've never seen answers to these questions that do it for me.

There was a series of Spelljammer books that I read ages ago, I don't recall the names. At least one of the books had, as a semi-main character, a beholder that somehow used illusions to make itself look like a man. It had found work on a ship... it was basically NG and had left its beholder colony b/c of ideological differences. The captain of the ship (the main character of the series) found out, and it was accepted as a member of the crew.
IIRC, the books didn't go into where the beholders came from, but it did have some fascinating commentary on beholder ideology. For example, each type of beholder thinking their type is the perfect creature and considering all other intelligent forms of life (
especially other types of beholders) as deserving to be destroyed. The different types were constantly warring. Granted it isn't cannon but it was very interesting.
I can't comment on the quality of the books... I enjoyed them very much in high school but that doesn't mean much LOL. Now I want to find them and read them again![/sblock]
On topic: As far as portmanteaus, I think I must have a pretty high tolerance as most of the words mentioned in this thread don't bother me at all. Then again, I haven't played 4e so I haven't seen the quantity that perhaps others have seen.
I personally like feywild and shadowfell; I don't really care for feydark and shadowdark but then again I have always thought underdark was a bit silly as well. But I don't think they're horrible... just ok, instead of great.
There are plenty of good portmanteaus that, like shadowdark, have essentially the same word twice - for emphasis. Keep in mind too that many languages instead of saying "more dark" or "many rivers" would just say "dark dark" or "river river". So that alone I don't think would qualify a word/name as "bad".
Of course, I am a bit biased. I come from a town that, when translated into English, is called Water Water (there are a lot of creeks and rivers).
