How to unlock History of Deponia
In Act III, you will find three mosaics – one in the Lobby and two in the Concourse. In front of each is a hatch to put the glowing phosphor cotton candy (use the phosphor cotton candy with the lamp in the Concourse to make it glow). Once the mosaic is lit, have Rufus look at it to describe an event in Deponia history. Once you've looked at all three (one will need to be cleaned for story-progression), the trophy will unlock.
