The Firehearted are spirits that dwell in the Fireheart, the realm of Malvar. They are silhouettes made of fire and are shaped like they were at the prime of their lives while wielding the best weapons and armours that they remember wielding in life made out of magma. Every time they die they turn into chunks of Malvarite ore.
They spend most of their lives training or fastening the chains to keep the god imprisoned in the Outer Fort of Fireheart. Around every decade one of the chain gets loose and he gets one of his limbs free and the Firehearted have to fight until he tires himself out and his chain can be re-fastened. Every time this happens thousands of Firehearted die leaving chunks of Malvarite splattered on the outer fort wall's.
