You know something? With the discovery of the 'tendrils'/'feelers', I think I finally feel like I have discovered every physical detail of my inner-self... Wow.
I know there is still much to learn - about the species' culture, their history, their language, their planet, how physics worked, what other creatures existed there, etc. - and I accept that I may never remember/learn everything about it in this life, but I feel a sense of satisfaction and peace I've never experienced before, not like this. It's...nice. Not an overwhelming feeling that hit me hard, more of a subtle washing-over-me type of thing, like having a warm blanket drawn over you. It's a sense of comfort.
