A crossroads somewhere in Sanus was a place for an important fight. Cinder, Emerald and Mercury found out the location of the then- Fall Maiden Amber and set up an ambush for her. They ended up defeating her but during the process of taking her powers, Qrow Branwen stepped in and severed the connection before it was completed. Cinder's faction quickly retreated and Qrow was left to take Amber to Vale.
In "Burning the Candle", Yang tells Blake how she found a clue about her mom, and when she was little. She took Ruby with her and walked for hours before finding an old abandoned house in the woods full of Beowolves. Luckily Qrow was there to save them.
As this is in walking distance of Yang's home it is likely on the island of Patch
It's implied that Raven Branwen may have lived there for a short time, as Yang apparently found an old photo of the Old Shack with her mother in it.
Sun Wukong illegally traveled on one ship and escaped into Vale.
This small settlement is located on the shore of the ocean, surrounded by hills. In addition to a large dock, there is a windmill next to the harbor.
The ship driven by it's Captain that takes Yang Xiao Long to Anima in search of Ruby Rose docked at this port. Yang got off and drove into the countryside on Bumblebee, looking for the bandit tribe led by her mother Raven Branwen.
No clue has been given as to exactly where this port is located. However, based on the size and shape of Anima it is likely that this port is on the western coast. The large southern, eastern and northeastern peninsulas of Anima would make for a very long voyage for the ship if it was on the eastern coast, and it would be faster to simply drive across the continent from the west.
Village West of Mistral
He needed information and, tired from battling Grimm along the way, he decided to start his search at the town's inn. The place was crawling with lowlifes and thugs, even a few Huntsmen that were most likely hired by shady people for shady jobs
It is not entirely sure if this is a real place or if Qrow made it up for the story.
It was located nearby some mountains, and the orphanage itself was a barn. There were at least four other children there alongside Cinder. While she lived here, the other children and orphanage workers constantly abused Cinder and got into multiple fights with her.

Fort Castle was a location in Remnant that was the site of an important battle during the Faunus Rights Revolution. It was mentioned in "Jaunedice, Pt.2" and has yet to physically appear in the series.
The Battle of Fort Castle took place in the third year of the Faunus War and was regarded by historians as the war's turning point.
The leader of the Human forces, General Lagune, sent his army to take the Faunus position at night, attempting to take them by surprise as they slept. However, he failed to account for the near-perfect night vision of his adversaries. Lagune's army was soundly defeated, and he himself was captured.
Due to this, the Faunus managed to start turning the war in their favor.

After that, she was ambushed by Tock and her crew. Maria dispatched the three assailants but had trouble with Tock due to her Semblance. She managed to kill her, but Tock cut out her eyes.
The Void is a place shown in The Lost Fable. It is seen as an endless white plane and resides "between realms" as stated by the God of Light. Following his departure from Remnant, he brought Ozma here where he gave him his mission on uniting Humanity.
It's possible that the Void is supposed to be a representation of limbo or purgatory, places said to be located somewhere between the afterlife and the physical world.
