Even if the area is rather small, there are several Darksiders II collectibles that can be found in The Eternal Throne, but to do so, we must know their locations.
In The Eternal Throne we can learn new skills, we can talk to Ostegoth if we wish, and trade the relics we have found, or, we can simply complete the main-quest and leave towards a new region; but it is important to advance only after we get all Darksiders II Eternal Throne collectibles revealed by the game guide below.
Using the maps and the hints provided in this specific guide, we can locate all items faster, and eventually, we will be one step closer to unlock all corresponding Darksiders II achievements/trophies.
Stone of Resistance Location
Below the training arena from The Eternal Throne is a Serpent Tome. We go in that room and facing the Serpent Tome we look at our right to spot a Darksiders Stone of Resistance.
Its easier that we stand at the opposite end of the room, and a little bit to the right, because the stone is covered by a red cloth.
Relic of Etu-Goth Location
The collectable can be obtained only after we speak with the Dead King.
In the room where he is, we go behind his throne to find a Darksiders 2 Relic of Etu-Goth.
Book of the Dead Page Location
When we go outside The Eternal Throne, on the road to Gilded Arena (after we speak with the Chancellor) well come across a giant serpent with two heads.
In here we meet again with Ostegoth.
To his left (our right) there is a hidden Book of the Dead page in the corner, behind the skull vases.
Please note that Ostegoth might not be here afterwards, so if thats the case, then the page is to our left as were facing the monster and the exit door.
