Caele is one of all those Companion mods for Skyrim. Almost. I've been very disappointed in the follower/companion mods for Skyrim; most of them have been about photo model exteriors with no content or soul whatsoever. You know what I mean - plastic babes with makeup and perfect hairdos waving big swords like professionals. Where's the immersion in that? To be fair, there are a couple of good companion mods out there, but they're few and far between. Vilja is great, and the official Dawnguard companion Serana. I liked them.
Against this background, I started creating Caele. She's a character with content, personality and indeed - soul. Fully voice acted, with a storyline to boot, she'll hang along on your adventures in Skyrim and exercise some real barbarism with her two handed weapons. No photo model fun here or plastic babe with Lydia's voice pasted on. No, siree. Not to say that Caele isn't beautiful though.
There's more coming. In version 2.0 she'll be marriable and the quest will be expanded. We're planning for full Dawnguard and Dragonborn support as well and to give her a whole lot of more voice acting. Right now, she's a really playable, enjoyable, complete character and personality already; a somewhat psychotic killer barbarian real babe.
