Talion's Goodbye is a speech or poem heard during one of the game's load screens. Although this is not the confirmed title, it can be inferred due to its contents. Presumably taking place not long after his revival by the elf-lord Celebrimbor, the speech is given by Talion, who becomes increasingly flustered as it progresses.
As rivers flow and waters fall,
as oceans settle on board of call
your journey onto white shores glide,
and there you'll settle in with pride,
and to the Rangers who honored Gondor,
may your spirits find peace ashore,
and to wife and son and kin may those banks bring bliss with you.
May their sacrifice be a beacon to us all.
