Aja's Bane

Conan rose, still smiling, as if to reach into a near-by cooking pot; then quick as a cat he struck Aja a terrible blow with the heavy bone. The Bakalah war-chief slumped over, his skull crushed in, and instantly a frightful yell rent the skies as the Bamulas went into action like blood-mad panthers. ~ The Vale of Lost Women

The Bakalah who live on the border of Kush are known for their fearsome raids to take slaves and other captives. And none were more feared than Aja, their war-chief, a great brute of a man who was deadly with both club and spear. This bony club was allegedly used to kill Aja in a moment of betrayal by a neighboring tribe, and now adorns his very skull.
