Spell And Says
These curious devices were the result of a joint venture by Gnomish tinkerers and Elf Wizards. There are boards every few blocks and each is magically linked to a central distribution hub which is kept in a secret location (for security). When something newsworthy or urgent must be told, a mysterious figure known only as The Messenger pulses a magic beacon to each of the Spell and Says around the island.
They were first established 50 years ago in the island city of Tok. The maximum distance between boards in order for them to behave correctly limited the spread of their popularity, as on the mainland most do not live as densely as on Tok , or don’t have access to magic users willing to do something so mundane, or have nothing important to say. Also, most who are unused to city noise find the clacking sound they make to be disturbing
