There very clearly setting up Vrtra to be the fourth when we go to the thirteenth. (What do you think that secret project of his they kept mentiong was? A body for rift travel, duh) He was toe to toe with Shotla as the most important character in 6.1 and is clearly being set up for more Which only makes this argument funnier.

Like there doing what some want, introducing new important NPC's and working them in. But Y'shtola and Estinien were also there so it doesn't count
