"House of the Dragon" Season 3's first episode is going to be talked about a lot because of the big Battle of the Gullet and another big character dying.But fans of the books and Westeros stories might also be excited about a quick and easy-to-miss moment.
One part of the first episode shows dragonseeds Ulf the White, Hugh Hammer, and Addam of Hull waiting in an ambush to fight Aemond Targaryen and his big dragon Vhagar.
Fans of "Game of Thrones" might recognize the place where they're hiding -- it's the Isle of Faces, near Harrenhal.This place is very mysterious and few people dare to visit it.Things get strange for the group before they go to the Battle of the Gullet, and some of what they see might make "House of the Dragon" fans scratch their heads.
Here's why the Isle of Faces is so important in Westeros history and myth and who that antlered man watching the dragonseeds might be.
What is the Isle of Faces?
Ulf, Hugh, and Addam are told to wait on an island near Harrenhal for Aemond and Vhagar.
Ulf and Hugh get impatient quickly, and it's probably because of where they are.The island is called the Isle of Faces and is one of the more mysterious places in Westeros.
The Isle of Faces is in the middle of God's Eye lake, which is very important later in the "House of the Dragon" story.
But few have ever been there.It's considered sacred land and one of the few places in the region where weirwood trees still grow.
During the Dawn Age, long before "House of the Dragon", there was a big conflict called the War of the First Men and the Children of the Forest.
The two groups fought for centuries and finally signed a peace pact on the island.The many weirwoods had faces carved into them so the gods could see the signing.The Children continued to live on the island after the war.
Who was that antlered man?
In the Season 3 premiere, strange things start happening as the dragonseeds wait on the island.
The turning point is when Ulf goes off alone and runs into a black goat, which is Alys Rivers.Daemon also saw the goat when he was wandering through Harrenhal.The moment that will excite longtime Westeros fans comes after when Hugh and Addam see something strange.They hear their dragons get disturbed and come around a corner to see a tall man with antlers and what looks like goat legs watching them before quickly disappearing.
This is likely one of the Green Men.
The Green Men were an order created to protect the deeper forests, trees, and the Children after the war with the First Men.
Because the Isle of Faces was considered a sacred place for so long, whether the Green Men really existed or still existed has been a topic of debate.
Their exact appearance is unclear.Some stories describe them as having dark green skin and antlers, while others suggest they wore green robes and antlered headdresses.
The brief run-in with one of the Green Men is in line with George R.R.
Martin's book "Fire and Blood." In one version of the story, Addam landed on the Isle of Faces alone with Seasmoke and spoke with one of the Green Men.
How it connects to "Game of Thrones"
The Children of the Forest, who signed the pact with the First Men and lived with the Green Men on the Isle of Faces, appear in Seasons 4 and 6 of "Game of Thrones." Bran meets them north of The Wall while searching for The Three-Eyed Raven.
The survival of the Children in "Thrones" seemed to confirm one long theory that the Green Men helped protect them from attacks from the Andals when they showed up in Westeros and got them off the Isle of Faces safely.
