Three distinct clues:
You don't look so regal
(Queen Elizabeth is a popular figure and pops up pretty much the second you google "Elizabeth")
Sitting upon your throne of ash.
(Ash, color reference is solid)
Your curved crown is slipping
(Unicorn horn, solid reference)
Clues that are iffy for me:
Surely, like those 115 bodies fell.
(1/15 has to do with the date that she was inaugurated, not with bodies, so this clue was confusing. It also pointed to another clue with the name reference, so it was basically a repeat of the first clue. As for the killing portion of the reference, that was good, but still had nothing to do with the number for me)
Regardless, I feel that the iffy clue was not misleading either, just not solid. Thus why I give this stealth a pass.
