Luminescent beings and elemental guardians, in ethereal forms, joined the champions in the cosmic dance.
In the heart of the realm, the champions encountered cosmic entities—embodiments of celestial alchemy that resonated with the champions' essence. These entities acknowledged the champions as alchemists of the cosmic tapestry, entrusted with the responsibility to transmute the energies of existence.
