Bran the Blessed - Celtic God of Rejuvenation and Protection, Lord of Ravens. He died protecting modern-day England, but his severed head continued talking and giving advice for several months afterward. When it at last stopped, it was buried in the White Hill, where some say the Tower of London stands today. According to folklore, that is why ravens still guard the Tower of London.
Autumn. Fallen leaves and stag's skull. The Stag, who represents the horned fertility God, has symbolically decomposed along with the autumn leaves as nature shows no sign of life until the next green spring when new deerlets are born, and the cycle of life picks up again.
