Kingdoms of Amalur: Reckoning - Echoes of the Past

You will have to travel a little ways to the S so hopefully you hit a point of interest while you moving around down there. Make your way to the S and over to the Quest Marker to the W. When you get there, talk to Alyn Shir and then step into the giant shadow. This will teleport you to his island.

When you get there, you'll encounter a lot of Son of Laz enemies. Remember fire and AoE attacks work well on them. Make your way to his castle and when you get inside, you'll encounter even more of these things. Kill them and make your way up stairs. You'll find some Faer Grota now too. Kill them and make your way across the upper level until Alyn Shir parts ways with you. It's a rather linear trip up to the top with no real resistance. There is a tripwire trap in a doorway a little further on but you won't encounter a real fight until you come to a large, round room drenched in green. Here you'll fight some Faer Grota and Ancient Leanashe.

After you are done with them, continue climbing and you'll get to Ventrinio. Talk to him and you'll be attacked by more Laz and Leanashe. Kill the first wave and then when the second wave appears and things get a bit crazy, feel free to Fate Shift. Kill everything and you will be sucked out of the tower as it collapses. Talk to Ventrinio to figure out what's going on, and then head back to the mainland.
