The main aim at Corabanti is to get the crystal in the building.
The crystal is behind a gate.
To lower the gate, the giant wheel inside the building must be turned.
To turn the wheel there must be power.
The power is derived from 5 volcanic pumps.
There are 4 outlying sets of bridges surrounding the main island.
At far end of those bridges are islands, one of which has a volcanic pump.
You have to reach those pumps and turn them on.
Puzzle one is to get to the pumps. Puzzle 2 is to turn on those pumps.
Puzzle 1: Make a continous bridge to reach the pump.
Each outlying set of bridges are made up of bridge segments that are disarranged.
Each segment is labeled with a symbol.
On top of the tower in the building is a console that turns those bridge segments based on the symbols that you can see through the telescope.
Go to the tower and look through the window and study the bridge segment.
Make a plan of how to arrange the bridge segment so that you can reach the volcanic pump.
Then turn the bridge segments using the console symbols. Remember that you can turn them horizontally or vertically.
The console can be turned using the arrow at the base so you can find the symbols.
If you have anymore questions, please post on this thread and I can see what I have missed in explanation.
