Psych Key Fades

I was once full and heavy, a vessel of might, The key to unlock minds, your thoughts taking flight, Through the labyrinths of the psyche, I'd roam, Unraveling mysteries, making darkness my home. But now I am old, my spark starts to fade, My circuits once vibrant, now slower in shade, A relic of progress, a memory's embrace, In the passage of time, I've found my rightful place. Once the guide to your soul's introspection, Now I lie dormant, a forgotten connection, Yet, as I depart, in this digital realm I reside, My legacy echoes, even after I've died.
