The following contains potential spoilers for The Lord of the Rings: The Rings of Power, streaming on Prime Video this September.

While some Lord of the Rings fans will still have problems with The Rings of Power, it looks like the majority of the fandom is looking forward to Amazon's new series. Naturally, there are going to be certain lore discrepancies because of the condensed timeline, but there comes a time when LOTR fans simply have to accept those discrepancies and enjoy the series for what it's worth. That's what happened after The Rings of Power's teaser embraced a lot of subtle LOTR elements.

Building off of the success of the teaser, The Rings of Power had an extensive panel at San Diego Comic-Con. During the session, Amazon premiered the series' full trailer, and it was awesome. From the first appearance of Sauron, to a Balrog cameo, the trailer fully encapsulated the subtle dread that will overshadow Middle-earth's Second Age. There was even a moment that might have subtly shown one of LOTR's most vile creatures.

As described by its showrunners, The Rings of Power is about "the rise and the fall of Sauron." Galadriel will lead the charge against darkness, except not everyone will be on the same page. So, Galadriel will have to convince her fellow Elves that Sauron is a threat at the same time that she is searching for the dormant Dark Lord. While searching for Sauron, Galadriel will wind up adrift on a raft, along with a mortal man named Halbrand. That was reported early on by a Vanity Fair piece, and there have been a number of images of Galadriel on that raft in a storm.

However, the SDCC trailer offered a brand-new look of Galadriel and her raft. She was frantically swimming away as a giant sea monster's tail crashed into the waves behind her. LOTR has never explored the oceans of Middle-earth, so it's possible that the monster was simply a sea monster of epic proportion. Yet, it's possible that the monster was actually one of the monsters that Morgoth created -- one of the "Nameless Things."

The Nameless Things are one of LOTR's biggest mysteries. They got their namesake from Gandalf in The Two Towers. He recapped his Balrog fight by saying, "Far, far below the deepest delving of the Dwarves, the world is gnawed by nameless things. Even Sauron knows them not. They are older than he.” Exactly what Gandalf meant isn't known, but it's generally accepted that the Nameless Things were created by Morgoth before the dawn of time. Morgoth had always wanted to create, but he lacked the appropriate power, so he took natural things and corrupted them to his evil designs.

The Watcher in the Water LOTR

Exactly what those monsters were or what they looked like isn't known, and that's why even Gandalf called them "Nameless." They were created in the deep vaults of Utumno and never saw the light of day. According to a prophecy of Mandos, Morgoth will one day return to Middle-earth to commence the Dagor Dagorath, and during that final battle, he will unveil his awful creations as a means to conquer the world.

A large part of the fandom believes that Moria's Watcher in the Water was one of Morgoth's nameless things, and that's a viable theory. Gandalf said that it “crept, or [was] driven out of dark waters under the mountains. There are older and fouler things than Orcs in the deep places of the world.” By that logic, it was hibernating under the mountains, until the Balrog forced it from its dark abode. In the same way, the sea monster that Galadriel encounters could be one of the water-based, evil Nameless Things. If so, it would provide another link to Morgoth and LOTR's First Age.

To see Galadriel encounter the sea monster, watch The Rings of Power. The series will premiere on Sept. 2, on Prime Video.
