Born after the Third Host of the Elves had traveled past the Hithaeglir, he saw many wonders, the Anduin River and the land about it, but also trembled from the sight of the Misty Peaks. The twilight stars made him joyful, the chirping birds made him sing, and the swaying tree-branches made him full of wanderlust, yet he hadn't wanted to go his lonesome. Once they arrived in Beleriand, the overwhelming sight of the various forests made him quite intrigued. But not yet would he walk among them. After Elwe had disappeared, he and his parents sought to find him, yet missing the journey to Aman.  despair and desperation took him, so he wandered the forests alone, and still found him naught. In due time, however, promised him harvest as Elwe, now named King Elu Thingol of all Beleriand and it's creatures, brought his people amongst him to Doriath. It was but the center of all Daerthion's interests, as the Elf liked indeed the forests and rivers. After the construction of Menegroth, he traveled in and out of the city, keeping an eye from whence the Dwarves of Belegost dwell, for he trusted not the 'uncultured' destroyers of all things natural.

His home swirled about a mighty holly tree. He enlisted the aid of fellow Sindar artisans to hollow his home, from which he sported many details. Flowers and plants and many more. Daerithion had not been in Menegroth when the Dwarves ransacked it, thus deep rage settled into the patient Elf. He hunted many Dwarves after the fall of Doriath. But what took him with fraught was the kinslaying and the second(and the last) ransacking of Menegroth. Elves fighting elves made him lose his sound of mind. Distrust of Noldor overwhelmed him for all the ages as well. Even forgot the safety and well-being of his family. Afterwards, he ran amongst the forests until  the reassuring songs of friendly animals had calmed him. He went to the Havens of Sirion where he dealt with Cirdan's people. At the destruction of the Havens from the hands of the Third Kinslaying, he fled to east of Beleriand, back to Ered Luin where he dwelled for some time. Now his eager feet leads him about the lands.
