Caladan Brood is a warlord who had the appearance of a Barghast. He was a longtime friend and companion to Anomander Rake. His primary warren was Tennes, but he also had access to D'riss and High Denul. He carried Burn's Hammer.
During the Malazan Empire's attempts to conquer Genabackis, Caladan Brood led a unified force of Tiste Andii, Crimson Guard, Rhivi, Mott Irregulars, Barghast and soldiers from the remaining Free Cities against them. Under his command, his forces managed to delay the Malaz 5th Army from completely conquering the north of the continent at Blackdog Forest for a period of two years.
He allied himself with his former enemies, the Malazans, in order to combat a more powerful and revolting foe, the Pannion Domin. Second in command to Caladan Brood was the once High King Kallor. Attached to the warlord's forces are a number of Tiste Andii sorcerers.
After Anomander Rake's death, Caladan Brood carried his body to a barrow outside Darujhistan prepared by Burn, and sealed it with a Barghast glyph that meant Grief. He then took the sword Dragnipur and shattered it with his hammer.
I was revealed that at the time of the events in Forge of Darkness, Brood was a highly skilled Azathanai mason and was hired by Anomander Purake to aid in the binding of Andarist and his betrothed in marriage by building the hearthstone for their home. The stone was inscribed with an Azathanai blessing that would only be known by the new husband and wife. At the time of placing the stone, Brood demanded an oath from Anomander Rake which prompted Rake to demand one in return. This created a bond between them and ultimately lead to their longstanding companionship.
