Main lore:
Lahmu was a regular bugbear surviving in a cave of a distant desert. One day he decided to enter deeper in the cave; he found a hidden hoard containing many treasures, including a mysterious ring. When Lahmu put it on his finger while inspecting the hoard, he had contact with a magic and powerful entity, a fire Ifrit genie named Al-Ghul; it promised him great power, but in exchange, Lahmu would allow it to possess his body occasionally, in this way, the genie would have a physical form, being allowed to sense, taste and smell; things that a natural spirit like a genie can’t do by itself, trapped between physical and spiritual realms. Finally, Lahmu being naive, he accepted the pact and the genie as his patron.

Combat:
To “obtain” its genie powers, it gave him a gem to wear on his forehead, creating a mental link with him and the entity. In this way, each time Lahmu needs to throw an spell, the gem of his forehead activates and the genie partially possess him, acting through his body and casting its genie spells.
When combat becomes more closer, Lahmu pulls his ring from his finger, transforming it into a giant chakram surrounded with spiritual fire. His attacks are fast, heavy and savage, moving the chakram around his body in a wild and mystical dance, cutting his foes appart.
When the fight ends, Lahmu knows how to tame his patron influence, moving it back into the ring with his trained willpower.
