Spoiler for the waterlogged side quest follows:
Guldun's intricate looking glass turns out to be a trick of the light. Is there a way to find one for him in the game or is it just one of those bitter endings?
Is there something to be found once the "Overflow basin is empty. Interior available. Minimal flood damage."?
01 Answer
Threre is an optional part to this quest which results in a trophy, but it is not to do with this.
Once the water is drained and the interior is available go to the lowest level and find a door that leads to a room containing a simple water flow puzzle (your focus will help find where to look). Solving the puzzle will give the 'drained the flood' trophy.
