In Destroyer's Expedition Link is 17 years old, and lives just outside of Hyrule Castle Town. He lives in a cabin with Epona, just a short ride from the castle. Link is an engineer, though trains aren't used much any more. He wields the legendary Master Sword, and, in my stories, one of the six ancient Hylian Shields.
Epona: Link has always known her, he has been riding with her since he could walk.
Zelda: Link has strong feelings for Zelda, but is afraid that she doesn't share his feelings.
