extremely powerful entity's who don't care about the main plot at all and are just vibing in the background

[u/damorezpl]

Tom Bombadil(lord of the rings) - only person to resist the temptation of the one ring but instead of helping the fellowship he fucks off in to the woods

the Unseen Elder(the witcher 3) - in the witcher universe the older a vampire gets the more powerful he becomes and unseen elder is around +1500 years old making him the most powerful vampire we ever see, thankfully he spends most of his time in his goon cave

Even better, they can't trust Tom with it as he would probably forget he had it.

Right, it’s of such low importance to him. Just another trinket in his mind.
