Azurerock

Azurerock is a common type of stone that comes in different tones of blue, it's used in construction and kept as charms by the riverborn people as a symbolic representation of the river.

Some believe you should bury the dead with a stone, or keep the stone near the burying grounds for a day and then throw it in the river to certify that the river will take the soul of the deceased to its destination.

Plenty of it can be found on the river bed of Silent Creek, especially inside riverborn borders.
