Which leaves me with the Nave. The Communal Spirit Nave is a strange organ, to say the least. Attached to the Vestibule, it acts as a signal booster, a force multiplier, taking the energy fed to it and strengthening it as it focuses and delivers it to… nothing right now. Once the energy exits the Nave it's dispersed into my body where the regenerative properties kick in, but the more I think about it, the more I think it's likely there's another component to these connected organs which I'm likely to be offered in a future evolution. I wonder what it could be? Maybe I should have poked through the evolution menu and looked for it… ah well.
