McKinley's Carnation

Origins
The true origins of this flower are unknown, but it is possible that it was left by Merlin, as his magic largely revolved around flowers. In 1843 it was picked by William McKinley.

Effects
The flower gives extreme luck to whoever holds or wears it, allowing them to overcome almost any circumstance. During the Spanish War, William McKinley used it to jam thousands of guns while pulling off his own ricochet shots, as well as causing a hitman's gun to implode and kill him.

However, the power comes with a curse. Once the flower is given away, all of the bad luck held off by the flower comes to the target all at once. In William McKinley's case, as soon as he gave it away, he imploded from a failed explosive that would have killed him earlier in his life.

Due to the curse, it is possible that this artifact is related to the Lance of Myag.

Placement
After William McKinley's death, his wife placed the carnation on the grave, and it was stolen by a young pirate, bringing it back for the empire that would eventually belong to Ten Beard.
