Echo's original body was human. Being a meditationist, focused inward, that original body was explored as thoroughly as a human mind can.. and finally one day was left behind, collapsing into dust. Echo is now a free spirit. As such, other bodies (usually provided by prior arrangement with the Puzzlebox pattern-storage systems) can be inhabited, and frequently are.
Interestingly, Echo could also appear to subdivide or multiply. Perhaps this was a quirk of being able to restore extra bodies from backup; new instantiations were sometimes called forth, all of them sharing each other's information in full. Thus, the momentary lone Echo was numbered zero, and additional Echos given increasing numbers. When only one was extant, it was designated zero once again.
At some point, Echo must have given up fear of Strange. Eventually, time was spent in meditation before the Statue there. Mel's encounter with the estranged Sebkha interrupted this, and Echo dedicated some time to the guardianship of Phys-FM. Eventually, that effort was decided to be unnecessary. Meditation resumed.
It resulted in a new transcendence. As such, Echo's public identity and capabilities are shifting to keep up.
Currently, Echo is made of bundles of ghostly tendrils; multiple location and extended awareness are all through the same being. Often a tendril might slip in out of nowhere to briefly converse with someone.
Echo is just a little arrogant, often assuming that most persons encountered have achieved the same level of fufillment (if not enlightenment). Emotional metaphors can occasionally be mistaken for physical declarations. Perhaps this is a cover-up or a ruse of some sort.
Ardra? is worth a mention here. A past lover, currently a very nice snugglekitten.
Camilla came seeking knowledge. It is willingly given, what little there is to give.
[OOC] Anyone who wishes to add themselves here is welcome to, including newbies - remember, Echo has been around a while; you might have met at some point. Name/link, brief comment.
Trilogee has had a memorable encounter: "Well, Echo was there while I got a memory put in. It was interesting. Echo has always been kind to me, at least as far as my limited memory serves. Everybody could use a friend that's willing to perform brain surgery with a mad scientist."
