I have finished my journey through Crossbell in the Legend of Heroes/Kiseki franchise. I started this series with Cold Steel 1-4 and got lost in the middle of 3 and 4 because of its story. This world the team built indeed relies on knowledge of events that happen in other games in this series. This experience for me was like learning I missed 5 whole arcs in a series when I started it. After finishing Trails from Zero and Trails to Azure, everything makes sense now.
