I name first 3 or 4 caps starwars, british navy, mythology, other sci - fi names and sometimes change them based on events eg. I had a lvl10 radiance that died named Void Dragon and its resurrected replacement (progenitor ultimate) was named wraith dragon oh and the progenitor got renamed Osiris' Word, or the kol that was renamed Vanidas' Hope after helping the Asteroid Vanidas repel repeated advent attacks.
