I'm taking the leadership feat now that we've reached 7th level, and I'm getting a cohort. I'd thought of doing this before and played with other ideas, but in the end I have to go this route. It's what makes sense and the GM says okay.
To begin with I knew my cohort needed to be a spellcaster of 'equal' strength to Amos, namely getting only 6 caster levels because I didn't want to go the "Now I am the master" route with this one. I didn't want my cohort to be weaker due to anything except the mechanics of the Leadership feat. So I started looking through all the classes and had no real luck, everything just didn't feel right. I bounced back and forth between making the cohort another bard or a summoner but it just didn't work. The cohort being a bard brought nothing new or interesting to the team, and being a summoner stepped on the toes of the already existing party summoner.
Finally I looked over it again and noticed something. Inquisitors were spellcasters? Well s**t, son, that's another option I COMPLETELY missed!
I looked at the spell list, it's amazing and perfect. So I started looking at the class mechanics and it all worked out rather interestingly. After that I worked some of the things together, giving my cohort a drive and purpose. Then I saw a deity from a third party source; Paletius. It's absolutely fitting to a near scary degree.
My next step was the character's nature. Basically flipped a coin and landed on the female option. Finally was equipment, and looks. I spanned the equipment available to her and then looked through some character art. At which point I saw this and set out to correct the differences of what I envisioned and what was in the picture. Not many were needed.

Later on she'll upgrade to different, stronger, armor and I needed to find an image for that to complete the picture in my head.

I'm intending breastplate, but this gave me the visual inspiration I required to carry on.
A young agent of a secret church, she's currently enlisted as a member of the Dalansgad military for purposes of access to the private library in the city and to keep an eye on the current happenings at the Lands Meet, an international meeting to levy for the trade routes in the oceans of the world. She came to know Amos due to his pursuit of knowledge and sees him as an ally to the church, as well as a great teacher of history. She wishes to learn more from him, but mostly she wishes to help with the current threat to the world.
Physical attributes will be rolled up a bit later, but now I need a name and I'm horrible with names. Suggestions?
