>traveler's sibling, tsaritsa, and pierro want to overthrow the heavens
>all of them seem to ignore the giant elephants in the room that are the multiple immensely powerful pure abyssal entities similar to Gosoythoth in act 5 of Natlan
Even if any of them succeed how the hell are any of them gonna deal with the tidal wave of abyssal monsters and corruption that will pour out when the protection of Celestia is gone? We literally see for ourselves in act four of Natlan what happens when a single one of them launches a full scale invasion, not to mention the entities in question only care for the destruction of everything and can't be reasoned with.
