RIP Lyndia well the first time I used the fire storm scroll and she exploded and the second tome I was fighting bandits and mistaked her for one
RIP Uthgred the unbroken first jumped in front of me swinging Chillrend second she got eaten by a dragon and third she attacked me when I first became a werewolf so I ate her face..... Really I did
RIP - Potential Follower Onmund He was mercilessly killed by my follower Mjoll the Lioness after accidentally hitting her with an ice spike while practicing in the Hall of Elements.
On one character I roleplayed a serial killer, and had a pile of companion corpses in my house in Windhelm. It was fun, until one by one they despawned
RIP Jenassa, I told her to we needed to part ways before doing the final companions quest. Was never seen again. And to Lydia, who vanished without a trace while being attacked by a dragon at a shrine.
Alleia the Huntress has died once or twice, I took the cheap route of reloading because I'm married to her and they won't let you remarry. Bethesda sacrificed my "realism" for me.
