who helps frodo and his friends escape from the barrow-wight
The Fellowship of the Ring In hopes of eluding the Nazgûl, the hobbits travel through the Old Forest. There the group fall asleep by a willow-tree and wake up to realize that its roots are trying to strangle them, but luckily Tom Bombadil comes to their aid. They then go to the house of Bombadil and meet his wife Goldberry. There they discover that the Ring has no power over Bombadil—he does not disappear while wearing it and can see Frodo even after he has vanished from his friends' sight. In the evening, Frodo has a dream about Gandalf standing on the pinnacle of a tower and then a vision of a rain curtain in front of a ship on which he is sailing. They then leave Bombadil's only to be captured by a barrow wight in the Barrow-downs, but they again escape with help from Tom and finally reach the gate of the village of Bree.
Gregor Clegane In A Game of Thrones, Tywin Lannister sends him to raid the Riverlands in retaliation for Catelyn Stark's abduction of Tyrion. Beric Dondarrion is sent to arrest Gregor, but Gregor ambushes and kills him.[6] He and his men continue raiding the Riverlands throughout A Clash of Kings. When Tyrion Lannister demands a trial by combat, the accuser Cersei Lannister chooses Gregor as her champion. Elia's brother Oberyn Martell is named Tyrion's champion for his own agenda to expose Gregor as a murderer. Oberyn wounds him with a poisoned spear, but the Mountain is ultimately victorious as he admits to murdering Elia and Aegon before crushing Oberyn's skull. Gregor's body is given to Qyburn for experimentation and he is reported to be dead with his head sent to Dorne as a peace offering to Doran Martell in the wake of his brother's death. But following Cersei's walk of atonement, she gains a bodyguard named Ser Robert Strong who is of similar enormous stature as Gregor, and whose body is completely covered in armor.
