Hello! Shadowmere died for me a while back, somewhere up north in between a few and possibly underneath a glacier, i dont even know where he is at. I somewhere Shadowmere respawns in the pool you get him from, however UESP contradicts this fact, Uesp also makes it unclear about when he respawns again, as it says 15-20 days later, yet later on, says that no amount of waiting can make him respawn. Does that mean that he spawns 15-20 in game days passed w/o waiting? Tbh i'm very confused here and i have no clue which source to trust, anyone can come in with some first hand experience and help get rid of my doubt? I'd appreciate it very much, thank you!

this is something i also would like to know. So far pal once shadowmere is dead then thats it gone for good. SO FAR.

If he is in fact gone for good, i would be dissapointed, even though the DLC will add a new mount, Shadowmere is the only horse for me <3
