"Brack was just a young'un, when the white trogs caught Brack's family in the caverns. Brack ran. Brack did not look back."
Brack was an old hammerhead who was a member of the Shadow Clan. When he was young, his family made the mistake of venturing into the Water Caverns. The white trogs caught his family and devoured them. Brack was young and agile enough to escape, but none of his family survived. He bore a large tattoo on his chest which represented this encounter, showing a giant white trog eating a hammerhead stick-figure.
