OK but lowkey wouldn't it be kinda sick as hell for eragon to 'resurrect' brom?
Maybe this is just me, but I've always thought that the discussion about trying to revive brom at the end of inheritance (iirc) was really intriguing. This is assuming that it's actually done as a way to bring him back and not like a horror downturn arc for eragon where he half fails and brings back a half alive brom or something.
Like, if the diamond tomb truly did stop his body from aging as the book implied, then he would be only a few hours passed once retrieved from there, no? Maybe after some huge battle with the new dragon rider generation and telling azlagur to go azlaguck himself he wants to show brom all he has done and let him see that the dragons are back, and that what brom sacrificed through the decades was worth it.
Would it be fanfiction-y? Maybe. I'd trust that paolini would be able to make it make sense. Maybe the ~~foreskin~~ thing that the menoa tree took was a metaphorical seed of love that eragon felt for brom, and now she's growing a new baby brom. Idk lol that's kinda silly but like you see how it could be incorporated.
I feel like it could work (not saying my way, I'm a bad writer, just any way that it can work) but also maybe it's a terrible idea. Thoughts?
