And Tirek.

Hmmm... Tirek and Discord can't be killed through violence or magic, but can Celestia and Luna? We know they have the "eternal youth" kind of immortality (like Elves on Lord of the Rings) but what about the "invincible" kind? Have we ever seen something that could potentially kill them? Maybe why Celestia survived Nightmare Moon and Chrysalis's attacks... then again, if they were invincible, Nightmare Moon would've known that yet she tries to kill Celestia so the sisters are probably not "invincible" immortal, just "ageless" immortal
