Herid Fel
From A Wheel of Time Wiki
Herid Fel was an Andoran historian and philosopher who joined the School of Cairhien set up by Rand. Rand consulted repeatedly with him on the nature of saidin and how he might be able to cleanse it. Herid was often distracted by Min at these discussions.
At the end of 999 NE Rand asked Fel about the seal on the Dark One's prison, most notably how it would be possible for him to repair it during the Last Battle. Fel pointed out an inherent contradiction, namely that the prison needs to be completely intact when the Wheel of Time turns and the Age of Legends comes again, so the Aes Sedai of that time can create the Bore once again. Fel became intrigued by this contradiction and began thinking on how it might be resolved. He reached a possible conclusion involving 'clearing away the rubble' but before he could reveal more, he was killed by the gholam in his study, suggesting that the Shadow was aware of his line of research and considered it extremely dangerous.
