Father Time

"That is old Father Time, who was once a King in Overland. Now he has sunk down into the Deep Realm and lies dreaming of all the things that are done in the upper world. Many sink down and few return to the sunlit lands They say he will wake at the end of the world."

- Mullugutherum

Biography
Father Time was an ancient giant that once ruled the Ruined City of the Giants. At some point he sank down into Underland and was sleeping there, dreaming of the goings on of the overworld, when Eustace Scrubb, Jill Pole and Puddleglum found the lost prince. The travelers were told that when he awoke, he would have a new name. It is unknown what happend to him when Underland fell apart, although he presumbaly carried on sleeping. When the end of the world came Aslan called "Time" several times, which woke him up. He then helped Aslan end the world, in particular by destroying the sun by squeezing it in his hand. He was left outside at the end of the world, and did not enter Aslan's Country.
