Dragon Eidolon
Because dragons have a strong connection to magic, their minds can often leave an echo floating in the Astral Plane. Such an entity is extremely powerful but unable to interact with the outside world on its own. Dragon eidolons manifest in the powerful, scaled forms they had in life; most take the form of true dragons (albeit smaller), but some manifest as drakes or other draconic beings. You have forged a connection with such a dragon eidolon and together, you seek to grow as powerful as an ancient wyrm.
