Optional Story:
When you arrive back from your mission to take down the Order of the Jigidi, you're met by a young girl who introduces herself as Katie. Nordh tells you he met Katie and her mother Cathy almost a year ago while working undercover inside Quiz HQ, a building shaped like a pyramid and home of the International Terror Heathens, or ITH for short. Even though they worked there, it was noticable that the staff didn't have any idea what was really going on behind the scenes.

"While mom, Cathy, was investigating some strange things going down at the Quiz HQ she just disappeared", Katie explains. "I haven't heard from her in over a week, and she told me if things went bad I could always count on Nordh here to help me."
Katie hands you her Security badge from work. "You can use this to gain entrance to the bottom level of the Quiz HQ. Nordh tells me you did an excellent job undercover in the last place and if he trusts you, I do as well. So, please, find my mom and bring her safely back home."

Well, you asked when the next one was going to be, but you had at least hoped there'd be a short time to rest up between missions. And while you knew you had to take on ITH one day, this new development makes it even more important.

Ancient Egypt Passcodes to reach the next level

Ancient Greece Passcodes to reach the next level

Vikings Passcodes to reach the next level

World War 2 Passcodes to reach the next level

This Puzzle Agency story takes place in two different locations. Nordh will help you from the Puzzle Agency mansion to try and guide you to the top of the Quiz HQ pyramid. There will be a set of quiz-like ITHs that symbolizes the different floors of the pyramid. You must start at the bottom and solve the first 5 ITH links before you can unlock the next level. Between each floor a more proper puzzle has to be solved to continue on your way upwards.

Codes deciphered are used on itstoohard.com.

No more hints can be bought.

Hint system
You can buy hints for everyone to use by creating GAs and sending me links privately. Let me know if you're interested. The GAs will then be added as rewards for solving the different levels, and a hint(s) for that level will be added.
Level 1 (WW2): 1-4 points GA value
Level 2 (Vikings): 5-9 points GA value
Level 3 (Ancient Greece): 10-19 points GA value
Level 4 (Ancient Egypt): 20-29 points GA value
Level 5 (The top): 30+ points GA value

You can, for example, create 3x10 point GAs for a level 5 hint. Or 1x8 points can give you two hints for level 1. You can even make a train with someone else to reach a higher level if you hand them in together.

As an addition, it should be games. No clickteam fusion GAs ;P
Last chance to buy hints will be January 16th, after that I will remind all complete solvers to check the top for any new GAs that may have arrived so they have a chance to check them out.

If anything seems wrong with an answer, tell me what question it is and I'll give it a look. You can try to drop subtle hints on what the answer should have been.
