Anyway, in the final part of the solution where you said that
 I should enter the altar and with that killing myself and
 the druid it's not a good ending. I found a better ending
 which is using the Magic Cube on Lawson instead before
 entering altar on Druids' Chamber then you get a totally
 different ending.
 You will fly the rocketship with the three other druids and
 went home.
