The Crown of Thorns is the House icon of the Blood Congregation of Mhaldor. As the name implies, it is a massive crown of thorns twelve feet in diameter and is made from a black metal of an unknown alloy. Wicked, black spires serve as the thorns themselves while electricity sparks between them, coloured a deep crimson. The crown levitates above a large prism of black marble. The icon has been destroyed once in the past and has been re-erected since then.
