I am under the sea but not very deep, Sharp and colorful, where small fish sleep. Ships must avoid me or they may crash. What am I, hidden beneath the splash?

I'm known for my melancholy, A symbol of past druidry. You may find me in a cemetery Or where water whispers quietly.

Orange, round, and carved, Awaiting ghosts and trick or treat, Autumn's glowing smile.

A layered disguise. Akin to a size. For plated knights a dragon prize. Many to measure. Tipping breaks ties. I to X sets the standard. Musics glory reprised.
