"the blue eyed one"
"the other blue eyed one"
"the blue eyes white dragon"
"god"

"read "the blue eyed one""
Even though I'm a huge fan of dune I could NOT remember the name of a character even if I was being held at gunpoint; Yes, there's Paul, yes, there's Duke Leto, but everyone else with a forgettable name like i just remember as like "that old guy" or "the weird fat mf"
