(not * saves * doomed man * fleeing)

Flight cannot save a doomed man.

The word "trú" refers to a person who is doomed to death, who fate is sealed, who is "fey" in its archaic sense. This alliterating saying, which underlines the irrevocable certainty of this condition, is found on page 172 of FDG. See also "Ba robad do throich" and "Am trú-sa trá!" in this collection.
