Additional Info
This decoration is part of an achievement decoration set that can only be earned by completing the “All for One” achievement, which is completed by reaching Influence Level 10 with all all 4 of your Alliance Specialists, then interacting with the terminal at the start of a Star Fortress and finding all four interactable alliance Equipment Caches hidden around the Star Fortress.
When you complete the achievement you receive this decoration and three others x50 – there used to be a bug that would grant x999 though.
