[@Spoopy Scary], [@Dervish] and I talked a bit in private, so what he said are mostly what we agreed on. Here's my extra bits.

[b]Overall[/b]
[indent]Quality writing all around. You've spent 12 hours writing the sheet, and the quality shines through because of it. The only formatting issues I see are: missing underline for adept conjuration and Bosmeri, and maybe bold each weakness title (up to you here). Your polished formatting, lack of grammar and spelling mistake shows amazing attention to detail; great work.[/indent]

[b]Strength[/b]
[indent]Agreeing with everything you and Dervish discussed. Another angle to approach her Bals out berserk is to emphasize surprise and aggression over raw strength. Self damage is the right price for pushing her body beyond her typical limit. Not only is this a fair trade, but also gives her berserk a negative aspect that makes it truly something she despises.[/indent]

[b]Daedric Possession[/b] 
[indent]Just to clarify, the werewolf Dervish mentioned was actually imprisoned through a group vote; she was later killed off-screen. 

Now, my take on Daedra possession is that it requires some sort of trigger. Whether that be a shrine, an artifact or proximity to Oblivion due to phenomena like portals or the Planemeld. If you want to keep some possession action, you need to setup an extraordinary circumstance for it to happen. Maybe she wandered too close to a Bal shrine, or maybe she found a cult trinket and wore it without knowing. Should you choose this route, you need to make sure it ends when she gets to Dawnstar. Removing the trigger not only prevents Wylendriel from being overpowered, but also makes sense for her to be moving away from the cult/summoning location and/or throw away the Daedric trinket.[/indent]

[b]Voices[/b]
[indent]I believe Daedric princes spend so much time talking to the protagonists is because of their role as the prophesied hero/prisoner. For an average Jane like Wylendriel, big bads like Bal have better hobbies than watching her 24/7. Dervs does have a point in that she is actively shutting out Molag Bal, rather than a cultist embracing his voices. Since Martin dragoned himself to seal off Oblivion, importing anything Daedric to Tamriel is going to take more efforts than before. Sure, princes like Sanguine and Sheogorath can manifest on Nirn, but I've noticed their activities are restricted to indirect influences; tempting and deceiving over straight up attacks. The Dragonborn had to agree to the princes before they try anything crazy.

Here's an alternative; hear voices once and only once. Molag Bal only talks to her to seal deal and directs her on a path of rampage, then everything after become blurry flashes. Tying back to possession, the one-time Daedric lecture can be attributed to something like a nearby cult site. Wylendriel will not have any more voice mails from Bal, not unless Dervish or myself decide to revisit. She probably doesn't know that, and can continue to fear for more voices.[/indent]

[b]Conjuration[/b]
[indent]You guys got this all figured out. Keep it adept, add she was a novice before and introduce non-Daedric skills she uses regularly.[/indent]

[b]Mercenaries[/b]
[indent]Wylendriel can be officially employed as a medic and/or chaplain. The chaplain route is interesting because our company could use someone with religious knowledge to defuse our crises of faith. She can also be contracted by the jarl and attached to our mercenary company "temporarily". It's best we discuss her entry into the group after we've addressed all other concerns.[/indent]

[b]Dominion[/b]
[indent]The purges exist. Delphine claims [url=http://en.uesp.net/wiki/Skyrim:Malborn]Malborn's family is victim to it[/url]. [url=https://www.reddit.com/r/teslore/comments/1yro4g/why_do_the_thalmor_purge_valenwood_during_the_3rd/cfn83wo/]This post[/url] on TESLore subreddit has some good points that I'm going to adopt. I have no problem with your references of the purges.

The Dominion Wylendriel lived in was the [url=http://en.uesp.net/wiki/Lore:Aldmeri_Dominion]Third Aldmeri Dominion[/url]. It was founded in 4E 22, following a Thalmor backed coup removing pro-Cyrodiil rulers. So as Dervish have said, being born around 140 would mean she lived under Dominion jurisdiction since birth.

[hider=Dominion 4E 202-205 (Optional)]
[i]Fruits of Contention[/i] has custom lore from 4E 202 to 205 derived from the nations RP [i][url=http://www.roleplayerguild.com/topics/30768-the-elder-scrolls-rising-storm/ooc]TES: Rising Storm[/url][/i].

Basically, the expelled traditional Altmer monarchy came back to Alinor on 202, a previously exiled prince had confrontations with the Thalmor and there had to be a forced coalition government. Elsweyr rebelled and left the Dominion with Imperial support in 204. Cyrodiil tried to sponsor a similar uprising in Valenwood two IC months ago, but ended up invading and then signing an armistice dividing Valenwood. Hammerfell also joined in and fought major naval battles again Alinor. Three weeks before the current IC date, the Thalmor started a failed coup and was taken apart by the royalists. These royalists have now reformed the Dominion into the Fourth Dominion.

That ought to do it. Sorry for the delay.
