Does anyone know what are these two monuments for?
They were not used in neither of Galeed Plateau quests (and are also not related with the secret pillar quest).
The big pillar is for a hidden quest that unlocks a title.

Oh! Cool. Thanks for the info!
It’s only one of the two pillars though, isn’t it?
Yeah, just the big one. I have no clue what the smaller one is used for.
Tos.neet doesnt list it as being used on any quest either. https://tos.neet.tv/npcs/47106
