Legolas is a wood elf. His people had lived in the forest now called Mirkwood since before the Elves went west, to meet the Valar. They and the Galadrim, (the elves of Lothlorien) are of the Moriquendi, the elves of darkness. They never went west. Galadriel married Celeborn after she came back from the west. She was the granddaughter of the king of the Noldor. The Noldor, and the Vanyar (the Caliquendi, or elves of the light) went west. The Vanyar were mostly blond, the Noldor dark haired. The Vanyar never came back, but the Noldor did. Among the Noldor some married Vanyar, particularly those of the ruling houses. Galadriel’s grandmother was a Vanya
Then there were the Teleri, who did go west, but went late. (Galadriel’s other grandfather was the king of the Teleri who did go west.) They were very closely related to a lot of the Moriquendi, and some of them never did go west, because their first leader (Galadriel’s grand uncle) fell in love with a Maia named Melian, and he stayed in Middle Earth. Arwen is one of her descendants, as is Aragorn, although Aragorn is of the race of men called the Numenoreans. None of this stuff happens during the War of the Ring. It’s ancient history.
The rings were made after everyone who was coming back had already made it back. At the time, Sauron was not perceived as evil, but rather repentant of his former acts, and striving to repay the elves for his prior harm. He was a lying scumbag. Celebrimbor didn’t buy it for a minute, and kept his rings away from Sauron. Others were less skeptical. Sauron didn’t make the one until after the others were made. The three were hidden, but the rest Sauron captured.
A couple of thousand years later, the elves got the one away from Sauron, with the help of the Numenoreans of Gondor and Arnor, but it was almost immediately lost. Isildur dropped it in the great river Anduin, as he was shot and killed by orcs.
Keep in mind that Galadriel was around for this entire story. It helps to understand just how weird she really is. She is a very nice lady, but she has seen a lot of hard, hard places come down to smoke and ash. Tends to make a person a tad bit flinty around the edges. Especially when you get left in charge of one of the three most likely targets of the Dark Lord.
On the bad guys side we got Sauron, and an unspecified number of Balrogs. (All Maiar, a sort of hemi-demi-god). On our side, we have Melian, (a Maia who left a few millennia ago and ain’t been heard from) Bombadil, (who ain’t gonna play) and five wizards, (also Maia). Two of the wizards ain’t been heard from since the ship docked. One is evidently more interested in saving the birds than the elves, and one is a turncoat. That leaves her, and a half elf and the only wizard who seems to be doing a damned thing to fight the aforementioned Dark Lord and about jillion orcs, trolls, and a whole bunch of men.
So, let’s go easy on judging this lady, she’s had a bad day, for the last six or seven thousand years, and most of it isn’t her fault.
