This is a contact sigil for a Memory Temple assistant, based on the mineral robot body form. It will activate a part of your subconscious or a sleeping soul element and "incarnate" it into the transformative mineral body form.
A memory temple here refers to the construct used to organize large amounts of information using common memorization techniques. This provides an algorithmic personally adaptive framework for improved memory and learning. There will be an "avatar" form which you can communicate with, but it's actually just a part of yourself doing the work.
Activation may be intense, after revealing the sigil, look at it until the effect appears, then it is recommended to assume a meditative position and remain still until the download is complete. A lot of information will be picked up from your surroundings as your memory abilities are activated.
