This looks fun, OP!

I'll play.
My perception of each NPCs will of course be different depending on which character I roll (I.e: Through the eyes of my Lavellan who struggles with her new role alone in the midst of 'outsiders'. Or as my Trevelyan who would be more comfortable being around this 'Herald' business)
So,, from what little that we know and from my Lady Lavellan's POV.. Here goes:
Advisors
Cullen
---------
1. What's your general opinion of him?
Dependable Military General.
2. Are you wary of his Templar past?
Very much at first. The 'stories' she heard about Templars not hesitating to destroy a clan just to get their mages.. And it doesn't help that she's clan Lavellan's First.
3. Is he friend or rival?
Starting of as rival, but gradually become friends due to frequent interactions, because of her 'Military First' policy, making him invaluable to her.
4. Will you romance him? If so why?
She would LoL if he'd fallen for her, an amusing idea that the ex-Templar would fall in love with a Dalish Mage of all people. She'd probably enjoy it since it has the potential to mess up his mind a little. Yet when her heart began to sing his name, she knew she's in serious trouble. Don't know how this will end, tbh.
Josephine
--------------
1. What's your general opinion of her?
She knows her words well and perhaps one of the first person my Lavellan will warm up to. Any diplomat worth their salt should be able to break the ice nicely and Jojo is one of the best.
2. Do you think her attempts at diplomacy are helpful?
Sadly, she would spend most of her time in Skyhold, advising on how to deal with shem lords.
3. Is she friend or rival?
A friend.
4. Will you romance her? If so why?
She's in the friend-zone, so no.
Leliana
----------
1. What's your general opinion of her?
Always liked her. So no, I won't send her to that mission where she got caught then tortured (eww, had me realize that only leaves either sending the General in for frontal assault or have Jojo talked the Venatori to death. Hopefully Cullen will fare better >_<' )
2. Is her belief in Adrastianism a boon or a detriment to the Inquisition?
She can believe whatever she believes so long as she's loyal to me.
3. Is she friend or rival?
Looking forward to being friends. Again.
The Party
Blackwall
--------------
1. What's your general opinion of him?
... The beard...
2. Do you think he's overly concerned with protecting the masses?
His honour and desire to protect others above himself is what made my Inquisitor respects him.
3. Is he friend or rival?
Friend. Hopefully no ninja-mancing.
4. Will you romance him? If so why?
With my other character, a pro-reformed-circle and power hungry Trevelyan mage. Because I think their character will balance each other nicely.
Cassandra
---------------
1. What's your general opinion of her?
A shem knight pointing her sword on my neck. Hooo boy..
2. Do you think she needs to lighten up?
She needs a good romance
3. Is she friend or rival?
Will see, but my Inquisitor respects her very much and hope they could be friends. Eventually.
4. Will you romance her? If so why?
With my other character Dude-Quisitor. Why? Because she's Cassandra, that's why XD
Cole
------
1. What's your general opinion of him?
It will be interesting to converse with a Spirit, though a bit wary about him being a denizen of the Fade.
2. Do you think that his nature makes him too dangerous?
Exercise caution. Although she would still try to make effort to understand him.
3. Is he friend or rival?
Hoping to be a friend..
Dorian
----------
1. What's your general opinion of him?
First meeting would be: OMG you're Tevinter!! [Hissing]. But then after getting to know the guy, he might be her BFF. What has Thedas has gotten into? Dalish being friends with a Magister (poor girl scratches her head. Weird times indeed)
2. Will you support his goal to reform Tevinter?
She'd make many copies of Dorian if she could, so there will be an army of Dorian making positive changes to Tevinter.
3. Is he friend or rival?
Friend (pls let him be a goodfriend)
4. Will you romance him? If so why?
I will only play Dude-Quisitor once, so.. Sorry Dorian

may you find happiness in other people's Dude-Quisitor PT *hugs*.
Iron Bull
1. What's your general opinion of him?
Too much crazy.
2. Do you think you can trust him with the Inquisition's secrets?
Nope, he's a Qun and he loves his booze too much. It's when the alcohol starts talking that I'm mostly worried of.
3. Is he friend or rival?
.. Will see.. But if he's too much mayhem and hard to 'control' then maybe leaning more to rivalry. My elf prefers order.
4. Will you romance him? If so why?
Nope. Not my type.
Sera
------
1. What's your general opinion of her?
It will be interesting to know why she prefer to live amongst the shems whom many view elves as 2nd class citizen.
2. Do you think she's too immature to be reliable.
Will have to experience this my self.
3. Is she friend or rival?
Friend
4. Will you romance her? If so why?
Nope. She reminds me of my Bhaalspawn's sister too much (Imoen) except she's blond and an elf.
Solas
--------
1. What's your general opinion of him?
Thought about dragging him 'back to Dalishism' (is that even a word XD ? ) Yeah, he's neither Dalish or CE, I know. Even plan to romance the dude, but fate somehow decrees her to love someone else (in my headcanon, Solas is just much into the Fade and not her, LoL)
2. Does he spend to much time in the Fade in your opinion?
Nope. Will be interesting if we could compare notes.
3. Is he friend or rival?
Welcome to Rift Mage Club, Bro..
4. Will you romance him? If so why?
Still not sure due to the 'bro-mance' feels, but maybe.
Varric
--------
1. What's your general opinion of him?
There is only one Varric.
2. Do you find his fondness for Bianca, is sweet or creepy?
Sweet
3. Is he friend or rival?
Is this really a question? LoL.. As long as he doesn't go Anders crazy and blew up some building then yes. A friend.
Vivienne
------------
1. What's your general opinion of her?
Her title says it all.
2. Do you support her Pro-Circle stance?
Depends. As long as they leave the Dalish and their mages be, then MAYBE (depending how the game goes) My Lavellan is wise enough to know what works for her people might not be applicable to others.
3. Is she friend or rival?
Hopefully as friends, but judging from what article I red, it seemed that we may be rivals. She has her own agenda and so does my elf.
