[Saurreg]

A twist:

I seriously doubt Thingol would have aided the Noldor even if it were Finrod and Fingolfin whom begged him to. The Sindar had grown too proud and resented the the presence of the Noldor whom had arrived without prior warning and carved off masses of land for their own.

Supposely, if big Fëa was still alive when Thingol lusted for one of the Silmarils, would he not have mustered his forces in an attempt to crush Doriath? The might of a dark god had not detered him from making the journey back to Middel-earth, would a spell of a lesser spirit stop him?
