Hmmm..more adventures for the Hobbits?
Cool Tolkien's "Middle-Earth" history site
It's true about Gimli:
"Son of Glóin, he travelled from Rivendell with the Company of the Ring. After the breaking of the Fellowship at Parth Galen, he hunted Orcs across Rohan with Aragorn and Legolas. He fought at the Battle of the Hornburg, and at the Pelennor Fields. He is famed for his fast friendship with Legolas the Elf; some stories say that they sailed into the West together - if this is true, then Gimli was the first and only of dwarven-kind to come to the Undying Lands.

After the downfall of Sauron, Gimli led a party of the Dwarves of Erebor to Aglarond, the Glittering Caves of the White Mountains within the realm of Rohan. There they founded a colony, and Gimli became known as the Lord of the Glittering Caves. His Dwarves performed great services for the Rohirrim and the Men of Gondor, of which the most famous was the making of new gates for Minas Tirith, forged out of mithril and steel.
