Signal Academy

Signal Academy is a facility for training warriors, located on the island Patch, just off the coast of Vale. Ruby Rose is a former student of Signal Academy, where she forged and learned to wield Crescent Rose, but was moved up 2 years due to an invitation to join Beacon Academy. Ruby's Uncle Qrow is a teacher at Signal Academy. All students craft their own weapons at Signal.

Ruby Rose
After Ruby Rose tries to stop a robbery from a local shop by Roman Torchwick, she is brought in for questioning by Glynda Goodwitch and Ozpin. When asked where she learned to fight the way she does, she answers that she learned at Signal. Ozpin questions this as her skills are well above what Signal should be teaching. She then admits that her Uncle Qrow, a teacher at Signal, had actually taught her how to fight using her weapon. Later, when flying to Beacon Academy, Ruby says she can see Signal from the airship.

The Shining Beacon, Pt.2
The night before the Initiation, Ruby writes a letter to her friends back at Signal in order to tell them what Beacon is like. Yang teases her a bit, but Ruby objects by noting she didn't get to bring her friends when she left Signal and how it was odd to not have anyone else with her that she knows at Beacon.
