I can think of several quests one can partake of in Mount Celestia, but I have scoured through much of the lore of the plane so I know of all the different things one can encounter.I don't know if others have the same mindset, but that plane as written in my mind seems devoid of reasons to use for adventuring. Don't know if its a mental block of its actually been written in a way to discourage using it for adventure.
A plane like Bytopia or Elysium, for comparison, have far less potential for interesting plot hooks in my opinion.
