Go to the purple door in the Nexus. (It should be the first door on the left after you come up the ramp.) Examine the purple rod with your magnifying glass and input the shape and color combination in on the control panel. The door will open. Enter the open door and press the mystery button on the wall. This button is the tram call. Once the tram arrives, get in and let it take you to the spire. When you finally arrive in the spire, you cannot open the weakened door. You will be able to later, once you get some help from a certain dead person. (?) Go outside and go up the path. Ignore the water for now. Click on the strange device located on the pedestal. Press the button for approximately 5 seconds, and a light bridge will activate. Next, enter the door to the museum. Pick up the glowing crystal, and the tablet first. Look at the displays. They will give Boston(you) hints on how to solve future puzzles. There is also a red engraved rod above the library door located in the far end of the museum. Don't forget to pick it up. After these tasks are done, go back down to the nexus and use the glowing crystal on Brink. He'll come back to life. Now that you have Brink again, go back to the tram. Once you are in the museum spire, try to open the weakened door.
