Ogar was a Dwarf from the Iron Hills. He lived there with the few Dwarves who had not moved to Erebor. He was very good friends with Ronin Silverore. He was a fierce fighter with both an axe and a sword and is said to have killed 57 Orcs in the Battle of Five Armies. He, along with Ronin, came to Erebor after the Orcs invaded the Iron Hills. Together with Skargim they defended Erebor from the Orcs and were able to reveal the location of the Orcs’ caverns.
