I think you're wrong, it's a lower case lambda. I'm pretty sure it's a reference to anonymous functions in lambda calculus. They're functions that aren't bound to an identifier. I personally think it's a subtle reference to the idea that there are three warframes that aren't bound to a tenno and opperate independantly. I've got a couple ideas about how that might work, but it's all deep conjecture.

It might be far fetched, but this one possibility for what I imagine might be going on. The Umbra frames were the warframes actually used to kill the Orokin Emperors and when the Tenno devoured their Oro, something happened to their warframes and they became completely independant. It's possible they killed their Tenno, maybe even devoured their Oro. Or another possibility is that the trauma of witnessing the betrayal of the Tenno caused some warframes to reject their Tenno and sever transference.
