Aliya the Perfect.

As a young Vedalken, Aliya always had a fascination with one question:  "Why would anyone try and perfect their own creations, when they themselves were far from what they were trying to achieve?"  Thus, she vowed to never hold any tool before she had reached the peak that is perfection, but the vedalken curse is always knowing that nothing can ever be perfect. Even to this day, she hasn't invented a single apparatus, going completely against her kaladeshi nature.  

One day, when one of her female clade-member that she was especially close to died in a horrible accident, her spark ignited. She arose on the plane of Bant, where she fell in love with a new concept that would shape her life from this point forward;  "Perfect Justice."  For years Aliya trained with the knights of Bant, developing a close friendship with Hamia, also known as the Blood Diamond.

 Her sense of justice and vigil quickly arose her to be one of the most elite of the Sigil knights to ever have existed on Bant, earning so many Sigils that she refrained from wearing them as the sheer weight of them was twice than that of her own, which would slow her down.  Her sense of Perfect Justice and her skill with the sword eventually caught the attention of Phemeskara, who was looking for a new candidate that would become a commander of Felldawn.

Aliya figured that she could help more people across the multiverse with her Perfect Justice if she accepted this offer. In time, she would become one of the strongest commanders throughout Felldawns history, mentoring both Shizuka and Mara as her lieutenants, the latter becoming her successor.  

 After hundreds of years passing by, Aliya saw flaws with how Phemeskara judged planeswalkers across the multiverse and felt that they acted too much on the grand scale while the civilians still suffered. To the disarray of Mara and Shizuka, who was very close to their mentor, Aliya suddenly left Felldawn without saying a single word to either of them. 

The most common theory is that Aliya and Phemeskara had a falling out regarding a certain planeswalking dragon messing with a distant desert plane.  Her current whereabouts are impossible to ascertain, but she is still out in the multiverse, perfecting her own body, swordship and justice.  It is said that she has taken on a new student, from the very same plane that the dragon planeswalker had destroyed and that Aliya had failed to protect.  Out of guilt or obligation, nobody will ever know
