The triangle trebuchet fodder=3 large marked stones surrounding the park , and to avoid looking within. Focus = 2020. Behind the throne = the hiding spot for the medallion. Leave = 1 oak,1 elm, and 1 maple leaf were glued to the top of medallion. In peace= graveyard.
I will admit a bit of a red herring here, as the park had only 2 benches and 1 had a downed power pole behind it. The true power was to be revealed in today's clue.
