The more astute or exploring players will by now have noticed a few changes made to Ember Isle when 2.4 dropped.
First of all, there's a new base on a small island called Breaker Point just to the west of stranglewood and it has it's own travel stone, but...it's underwater all the intriguing stuff is to be found.
There's a huge city now underwater called Ruins of Gakulos, also included is a big complex further north called the Temple of the Moon but the spectacular looking part is an underwater lave eruption and flow called the Dream Furnace. No one is speaking, no one seems to know what plans are afoot for Ember Isle
