Scattered across the surface of Ossus are a number of hidden unmarked locations, rich with their own unique detail, lore and treasures. This guide is cataloguing all unmarked locations of interest across Ossus, this categorises as locations that allow the player to interact with an object or part of the world in a specific and unique way. An example of this is unmarked lore, treasure chests and Ancient Tablets
Unmarked Location #1 - Lore Entry

Unmarked Location #3 - Treasure Chest

Unmarked Location #10 - Hidden Phase
Coordinates X 1372 Y -370
This odd little phased area is hidden just a bit further to the right of the Grappling Hook cave, the odd thing about this is that no quest indicates this phased area as of yet. Upon gaining access to the phased area, done through jumping over the rocks around the side it teleports you to an already used cave. Located by a heroic across the map.
Unmarked Location #11 - Ancient Tablet
Coordinates X -724 Y -259
This is another mysterious Ancient stone tablet, as similar to the first it exhibits an effect and sound when clicked. This is a little hard to see due to the dark location that it sits in, hiding behind a pile of rubble in the Jedi Temple Ruins.
Unmarked Location #12 - Ancient Tablet
Coordinates X 760 Y -515
This tablet sits half way up a snowy mountain at the northern most part of the Ancient ruins, not including the world boss location which is the furthest outcrop. To access this you will have to carefully climb the mountain, the actual jumping is quite easy.
Unmarked Location #13 - Ancient Tablet
Coordinates X 183 Y 250
This is the last and final tablet that has been discovered so far, strangely however unlike all others this tablet isn't clickable. Perhaps after the others have been activated in a certain sequence will this one become active.
