After some weeks, a series of posters make their way down to the Spire and are posted on notice boards. A number of them are water and moss-stained.

ALL YE WHO READ THIS, KNOW THAT:
OUR BELOVED DUKE IS DEAD!
Resting now in his eternal sleep, Duke Arthus has perished. In his place, his firstborn daughter
and rightful heir to the Duchy of Rulan is to rule!
Proclaiming herself rightful Duchess of Flowers, Guardian of the Wall:
DUCHESS DAHLIA SILVERBLOOM!
To celebrate the occasion, all are invited to pay a tribute to her rule.
A Walljack is quick to nail a small burlap sack below the notice board, to collect 'tribute'.
Safe to assume you're paying tribute to their pockets, though.
