Actually I've formatted it back:
Some random examples from other wikis
http://tf2wiki.net/wiki/Soldier
Information: a general paragraph or two, overviewing the subject.
Then below that, there's the Bio, containing multiple links to assorted other pages
http://fallout.wikia.com/wiki/Wazer_Wifle
Another example, again beginning with a general overview.
As I mentioned before, though, I believe a general gameplay-orented overview of the race, should come above the background info. But a big pile of links, like what you have, belongs down at the bottom, I would say. Or alternatively, in a sidebar, like the wazer wifle page.
I am not sure about your change with traits being listed under the leader. I think they should be to the right to save space. Remember, more info organized in less space is better if not too cluttered.
Saving space is irrelevant. Space is an infinite resource.
Arranging the traits under the leader name makes them neater, and more distinguished. Having them all on one line looks messy, and could especially be visually confusing for multiple word traits, like Cold-Blooded. Making each one a seperate line, indented in, shows clearly where each link begins and ends, and being indented under the leader makes it visible who they belong to.
Don't do tweaks which take more place while don't add content. At least in case of traits it reduces comfort of recognizing the connection between leader<->traits when there're more leaders than 1.
Again, formatting. Being visually clear and readable is more important than conserving screenspace.
More examples:

http://starcraft.wikia.com/wiki/Marine_(StarCraft)
Again, the links to lots of sub-topics, are in a sidebar, the page opens with a general summary, and the big pile'o links is down at the bottom.
I'd say, get that general info part into a sidebar, on the right hand side. It's tall but not wide, and is a waste of vertical area if it's above things. It would fit much better on the side. In fact, the widest part there is.... the leader traits, because you have them all on one line.
