OK, OK. Enough with the begging!
So...there were multiple Gods residing in Valinor (ie, heaven, for elves only, though also two hobbits and a dwarf), which is where ships sail when they leave Middle-Earth. The one big God (who created all others and the world) didn't hang in Valinor. At the very beginning he made two gods stronger than the others: Manwe and Morgoth. Then he made elves. One of the first was Feanor, Galadriel's dad. He made some cool jewels (the Silmarils). Morgoth coveted/stole them, killed Feanor, and enlisted the aid of a giant spider (Ungoliant, Shelob's ancestor) to escape the sight of the Gods and flee to Middle Earth. Galadriel and her brothers vowed to follow him to the edges and retrieve the Silmarils.
Most of her brothers died in the quest, typically either fighting Morgoth or his lieutenant Sauron. Finally the Valinor Gods got tired of Morgoth's schtick, led an army to Middle-Earth, and captured him. He was banished to the Phantom Zone. Sauron...and some Balrogs...escaped. The Gods tell Galadriel they're steamed she disavowed Valinor in her pursuit of Morgoth, and banish her to Middle-Earth. Much...much...later she realizes when she rejects Frodo's offer of the ring that she is forgiven and can pass into the West (ie, sail to Valinor).
Manwe had lesser Gods serving him. One was Olorin...aka Gandalf. When Sauron popped up and started agitating in Middle-Earth again, Manwe sent Gandalf and other wizards to counter. You might've noticed that whenever Gandalf got into trouble, Manwe's prize giant eagles bailed him out.
Tolkien's material could rival Marvel's. Hobbit and LOTR is but a teensy slice. Also of interest is how Sauron deviously led Aragorn's people/ancestors to destroy themselves. Anyway, everybody dies...even Arwen freaks out when it's her turn, as her dad predicted (Elrond wisely sailed to Valinor). Centuries/Ages pass, and Manwe's son, Fionwe, has a (likely) hot girlfriend. Morgoth either escapes the Phantom Zone or is released. He somehow kills Fionwe's girlfriend, and Fionwe, in his rage battling Morgoth, destroys the world.
Curtain drop. I wipe a tear and, now many years into my Tolkien study (and older than I care to admit), figure kissing girls isn't so yucky after all. I begin my pursuit and slightly-less-epic adventures. I learn that suppressing my Tolkien affinity increases my chances significantly.
