So, this is based on Duilin's story Forty Two. In it, she has Maglor try to describe his father in thirty words, and end up doing so in forty-two instead. Well, me being...me, I decided to take that as a challenge, and tried to describe Fëanor in thirty words. So, while she didn't make it a challenge, I am: Go read Forty Two, and try to describe Fëanor in only thirty words!
Fire
A killer, a lover
A father, a son
A creator, a destroyer
He crafted the flow of history
Like and with his beloved jewels
A flame that consumed itself
