Could you mayhaps do a quest for a mage of mind in the land of relics and memories, please?
Sure! So, a Mage of Mind’s Quest would involve learning and experiencing Mind, using that to solve the Land’s problems and reach the Denizen.
In this case, I would say that their Quest would likely revolve around using the Memories of/around/within the Land to learn of the Relics, and experience the perspectives and laws surrounding them. A lot of Mind Lands tend to seem to use puzzles of some sort, so I think in this case it’d surface as the Memories providing solutions to puzzles the Relics pose.
By solving the purpose/puzzles of the Relics, you begin to solve the major problems of the Land–which could be anything, but perhaps a lack of perspective/remembrance of the past? A lack of thought on said past?–and eventually reach the Last Relic, whose purpose/puzzle will reveal the last piece that will lead you to the Denizen.
Perhaps all of the Relics reveal a piece of the path to the Denizen? Putting it all together it could reveal a map? That seems like a possibility; lots of mind-twisting foreshadowing.
