-The left one is in charge of making tapestries that contained some vital life and the oldest of the three, each string and thread she holds contains ones' memory or in occasion, 'souls'. She has the ability to grant wishes and transfer ones' soul to another. She can summon 'battle tapestries' and turn them into weapons. She is very caring and acts like a mom to the other two. She holds the strongest magic of the three. I wanted to emphasize an 'older sister/mother goose/traditional fairy godmother' look for her appearance.
-The middle one is the youngest, she loves counting and she admires' her older sisters' tapestry. She claims her sisters are "close-knitted' with one another. She's in charge of guarding and sorting the 'life tapestries'. She is rather determined despite having no familiarity with weapons or familiarity with close-combat battles. Instead, she uses her magic to guide threads to battle. She can hold off an opponent by either using her magic to tie them up or locate the opponents' movements. I wanted to give her an energetic and cute look for her design.
-The right one is the 'middle' sister. She uses her needles, pins, and scissors to battle. Her movements were refined and graceful in the battlefield. She takes a liking to ballets and other graceful dances. She lacks any kind of magic in exchange of her swift and precise fighting abilities with weapons. She is rather distant towards the other two sisters and would rather fight battles alone. She usually sits on a high area, waiting for a perfect moment to strike. I tend to go towards a musketeer-like outfit for her design.
-They are loosely based on Moirai Sisters from Greek mythology and possibly fairy godmothers in Fairy Tales.
-insects are usually associated with strings and heavy symbolism in myths.
