Iceberg Outpost

Iceberg Outpost (流氷島, Ice Island) can be found to the far west of Harun Village, beyond the Lost Ship.

Go in the house and push the log right, then the other one down. You can now push the dresser out of the way so you can enter the door. Once you go through the door, a cut scene will start involving Ryu Kou and Hou Zan.

Near the end of the cutscene, Kraden will ask Ryu Kou for the Umbra Map, which he will hand over. Hou Zan will also be buried outside, with Hou Ju's Echo Gem as a grave marker.

Head to the left and climb up the tree so you can jump to the plant. Use Grow on it to continue. Climb up the right tree here and grab yourself over to the left to get the Mythril Silver from the chest. Now get back down and move around that chunk of land to get onto the roof. You can slide down here to grab the Mercury Djinni Rime. You can also find some Lucky Pepper too if you use the nearby tree to get up a level and check the box. We need to go around and get back on the roof, though, but this time jump down into the chimney. Here you can open the chest for a Minerva Helm. Push the log up and then right to get out.

Upon leaving, the team will talk about the Umbra Map, with Karis marking several places for us to visit. Rief will remind us about taking Ryu Kou back to Tonfon, though.
