Lazim is a mysterious character in the southern Kharidian Desert near the Quarry, and starts the quest Enakhra's Lament here, whilst posing as a desert sculptor. Though he is openly a follower of the god Zamorak, his true intentions are not revealed until the player has built him a sizeable statue with the head of a camel.
During the quest itself, Lazim attempts to trick the player into thinking he wishes to build a statue commemorating someone or something and, despite the notion that the middle of a desert is an odd place to build a statue, the player must oblige. It is then discovered that the statue was just a ploy, and Lazim was actually attempting to unearth a temple dedicated to the Zamorak-aligned Mahjarrat (and only remaining female of her kind), Enakhra. While the player goes through a series of puzzles, Lazim waits patiently, letting the unwitting hero find her and release her from her prison. However, Enakhra and Akthanakos, another Mahjarrat, aligned with Zaros and in battle with Enakhra, are both released and flee to The North, thus depriving Lazim from studying them.
After the quest, Lazim can be found in the top floor of Enakhra's Temple, and you can get another Camulet from him if you lose yours. If you speak to him otherwise, however, Lazim will say you've just deprived him of a wonderful chance to learn from one of Zamorak's first followers. If the Camulet is brought to him, he will offer to give it unlimited charges for 1,000,000 coins. This is a one-time fee.
