Questline

On Thanatos Tower 1F find the Representative NPC (tha_t01 149, 78) who is looking for recruits for those wishing to explore the tower. Sign up with her for the quest.
Talk to the guide on Thanatos Tower 2F (tha_t02 231, 161) to enter 3F.
On 3F (tha_t03 66, 67) you'll find a Rune Device in the southwest corner.
- Using a Lv. 4 weapon, you can pry the device open, obtaining a Red Key.
On 4F (tha_t04 191, 195) you'll find a second Rune Device in the northeast corner (tha_t04 185, 188) is sufficient if you walked from the portal.
- The device is visible from outside the wall.
- The mechanism can be opened by solving a puzzle, similar to mastermind if you've ever played it.
- The machine will guess 3 numbers between 1 and 9 (none repeating), and you will be required to crack the password.
- Each round you can guess 3 numbers from 1-9 (no repeats) and the machine will inform you how many of the numbers you chose were correct and in the proper location, and how many numbers are correct but not in the right location.
- You have 5 rounds to guess the correct code or you will be required to restart. When you correctly complete this puzzle, you will obtain a Yellow Key.
- Note: if you'd like help finding the number, try this site.
On 5F (tha_t05 59, 178) in the top left corner, click the Eagle Statue.
- Insert the Red Key into the crack, followed by the Yellow Key. You will receive a Blue Key.
On 6F (tha_t06 226, 226) in the very northeast corner, there will be a Gorgeous Statue.
- The dialog lets you adjust 5 wheels. You will want to adjust them so that they are all in the same configuration, one solution is:
  - First Wheel - Option 1
  - Second Wheel - Option 2
  - Third Wheel - Option 3
  - Fourth Wheel - Option 1
  - Fifth Wheel - Option 1
- Here you will obtain the Green Key.
Also on 6F (tha_t06 200, 181) walk south and you will find the last mechanism inside a fireplace.
- Choose the 2nd option each time to obtain the Black Key.
Once you've obtained all 5 colored keys enter the portal at the center to go to the next floor (tha_t06 120, 119).
- The Black Key will transform itself into the Black Charm Stone.
- Note: You cannot enter the portal unless you have all five Keys. If you have any Charm Stones, you must sell them at an NPC first, then collect the corresponding Key before attempting to enter 7F.
- You can now use the Warper.
