First of all, I will start off with a few questions that I'm hoping you can answer:
1. At what chapters do the main characters auto-promote? And does Sieg Auto-Promote?
2. Off the top of your head, where is the first Fel Contract in the game?
3. This is a big one, but nonetheless, I wanted to suggest it for you to keep in the back of your mind: The main last promise webpage should include a document with the location of all the seals/promotion items in the game. That is a big endeavor but throwing it out there nonetheless.
4. Aside from Tekun and the main characters, are there any other custom classes in the game? More specifically, are there any with custom animations (like Tekun/Kelik)
5. The boss battle music is epic, where can I get it? (such as the one where you fight howard)
Now the second thing I wanted to add involves the main last promise page and some of the errors that I found. I wanted to make it easier for you should you decide to go back and edit it in the near future. These were all of the ones that I found

Anyways, here goes.
1. In the recruitment document:
-Noah is a hero when he first shows up in chapter 7.
-Logan's class states swordsman, when he is in fact a myrmidon.
-It states Gordon as the cavalier that rejoins in chapter 16, but it is Corben. (I think its because gordon was his old name?)
-Siegfried's class says Knight Lord rather than Knight-Errant when he rejoins in chapter 17.
-(I'm only up to chapter 18 so i don't know about anything else.)
2. Broken Link:
-The Feshrine forum link doesn't direct anywhere.

Sorry for the long post... again. I wanted to be as specific and helpful as possible.
