The symbols around the lower boxes are
two Skyscrapers logic puzzles.
Rules of Skyscrapers (for a 7×7 grid): Place a number from 1 to 7 in each cell. Every row and column must have all digits from 1 to 7 exactly once. These numbers represent buildings of that many stories; outside clues count how many buildings an observer looking at that row or column could see. Higher numbers block sight of lower numbers.
The solutions to that part:
These solutions have an interesting property:
every possible pair of digits is used exactly once. These can be used as coordinates for the grid of runes: the first is the row, and the second is the column. The runes, transliterated, spell a message:
"Hero of Pellenor [sic] facing down despair? Yes and no."
this is a cryptic crossword clue. The definition is "Hero of Pelennor"; "facing down" is an indicator to reverse the next component, and "despair" is WOE. "Yes and no" are Y and N; together, these make EOWYN, the person who killed the Witch-King at the Battle of Pelennor.
