a mountain that walks, grain by grain, faster than empires fall
means A hill or ridge of windblown sand, built up and slowly shifted by the wind in deserts or along coasts.
from From Old French 'dune', borrowed from a Dutch word ('duin') tied to the same root that gave English 'down' as in the rolling 'Downs' of southern England — both tracing back to a Celtic word for a height or hill. The sense narrowed over time from 'high open ground' to specifically the heaped sand we picture today.
