Shire and Ev have a… TENSE relationship before the Envarian coup.
Shire joins the group during/around the Tartarun Civil Wars. He starts off as this young kid, fresh out from under his mother’s thumb, who does really well under the tutelage of the more seasoned leadership of the Northern Coalition (Nedir Al’verde) of Tartarus. He gets kind of awestruck by Ev and Talis for a while, but eventually grows out of it and becomes a very promising young leader once his mother dies and he takes control of Envari.
Then the rest of his arch happens, he makes some questionable new friends, and he… learns some things he shouldn’t, some of which are true and some of which aren’t. He picks a lot of fights with Ev as result, especially after he disavows the rest of their friend group. They kind of make an easy target, and because Ev is protective of their secrets and also still trying to protect him, they usually end up falling for his bait and argue with him. A lot.
