I have an elf queen (I'm pretty close to having her incoming, and I still haven't carved out her room, much less decorated it...) and she has a dwarven name, as well (Asmel - "merchant"). She is the only elf in legends with the name Asmel, which is held by about 9 dwarves.
Sadly, she's not even remotely as cool as Cacame. She has nothing but being a farmer to her name.
(As for world history, a nearby elf civ, The Bronze Cobra, somehow ate a goblin fort and a human city really early on, and went on to annihalate an entire dwarf civ. Because of the power of having all the races in vanilla DF under their control, they pretty much went on a world-conquering spree, stopped only by some goblin civs that have done exactly the same thing. My legends are filled with elves and goblins slaying each other by the thousands, as those civs have apparently limiltless cannon fodder. My own civ took an elf city and managed to reclaim some of the fallen dwarf civ's land, but apparently bled out, and the last dwarf king was a fairly decent warrior.
In Asmel's defense, she has not only maintained peace (the old dwarf king signed one before he died), but also done some major construction, creating dwarf cave-roads between the various dwarven cities, so I just presume she's living up to her name, and focusing upon mercantilism. It may not be as dwarvenly, but sitting back as the elves and goblins kill each other for you, and focusing on getting rich, safe inside the dwarfhomes IS fairly smart... and pretty much the way I like to play, anyway.)
(Also, thanks to the fact that the mountainrange I embarked on is home to 4 goblin towers, region history involves some absurd number of seiges, all of which go along the lines of "27 elves, 2 golbins, 8 casualties attacked 17 elves, 20 humans, 15 goblins, 5 casualties", with the overwhelming number of my engravings having elves being killed by goblins, and occasionally humans or other elves.)
I think this has to be my favorite battle that took place at the gates of a goblin tower - Ceca Coastalboarded, elf of a goblin civ, defeated an entire elf army single-handedly. Elves from elf civs SUCK!
