On endless ocean 2 where is valka castle

Valka Castle is in the Triton Village ruins,which is obviously in Ciceros strait,if you find a map of Ciceros Strait on a walkthrough site, find 'Triton Village ruins' and when you play your game,go there. The guy you met earlier on your boat will be there,and also the shark he told you about too,I think it might have to be night,i forget, but when something goes wrong,Oceana will tell you to go into a well,and you dive down there.Now,go forward to a big round room,and go up,go up until you reach two different paths,you will have found Valka Castle!
