I try to tune into TennoCon every year since I've started playing however one idea that stuck with me the largest was the idea of a Warframe inspired by the Three Fates of Greek and Roman mythology. The idea was brought up on a panel during the TennoLive by [DE]Pablo who mentioned wanting to do one and was one he always wanted to do. Fast forward a few months later and the idea comes back to me and with that idea I took to my tablet and began working away.
I decided to play heavily into the Three Fates theme, naming the frame herself: Moirai. The name being the original name of the Three Fates in Ancient Greece. The stances being named after the Three: Atropos, Lachesis, and Clotho. Clotho being the one who spins the threads, Lachesis being the one who weaves and measures the threads, and Atropos being the one who cuts the threads. I went hard with the thread motif in the design. Wanting to make a visual play on the phrase 'threads of fate' and so Moirai is a weaver of them. Weaving, sewing, and cutting threads as she so desires with the wills of her three selves defining her actions.
I never did write out her abilities, but I did design what I'd envision them to look like should she ever be worked into the 3D side. This piece also gave her an alternate helmet, the name of the helm being "Morta" which was one of the names of the Three Fates in Roman mythology.
