Malleus

Malleus, who was originally known as Telloti Cillmam'n, was a Force-sensitive Human male from Taanab. Born during the last years of the Galactic Republic, he was detected by the Jedi Order at a young age and sent to be trained at the Jedi Temple of Coruscant as a member of the Boma Clan of Initiates. At the age of thirteen, he fought in the Apprentice Tournament to attract the attention of a potential Jedi Master. Failing to be selected, he was subsequently deemed too old to become a Padawan learner. As was customary, he was forced to join the ranks of the Exploration Corps instead.

In 19 BBY, after seven years of service in the Corps, Cillmam'n was dispatched to Nicht Ka with Master Ekim Ryelli and Staguu Itincoovar. Once there, he found the armor and lightsaber of the ancient Dark Jedi Warb Null. After donning the armor, Cillmam'n was flooded with visions that made him turn to the dark side. Carried away by his newfound power, he dueled Ryelli, whom he ended up killing by decapitation, and, after disposing of Itincoovar as well, he left the planet. Now a Dark Jedi himself, Cillmam'n assumed the identity of Malleus, the Hammer of the Dark Side.
