Taboo on the dead

A taboo on the dead is a common practice among many cultures, including all of those within the Chronicles of Ancient Dankness universe. In this series, it is common clan law that one must not speak the deceased's names for five years after someone dies. Torak is well known for having broken this law over Bale's death, to Renn's severe disappointment. And now Bale's ghost is going apeshit, driving the world insane without even knowing who he is.
