Boaz And Linus.

Boaz and Linus, Twins of the Dark Moon, One Sad, One Happy, One Lazy, One Energetic, both of them are the opposite due to both being legends, they were said to be born straight from the core of the earth and sent immediately to the volcano as a sacrifice, but due to them being so special, they just disappeared into thin air, after 4 years of their birth, they were never to be seen again in this world, they might be considered legends, or Outer-Gods. (Message: I used medieval translator to do the sentences lol.)
