In aSoS, Melisandre reveals knowledge of a prophesy, regarding a red star bleeding marking the second coming of Azor Ahai.
"It is written in prophecy as well. When the red star bleeds and the darkness gathers, Azor Ahai shall be born again amidst smoke and salt to wake dragons out of stone."
Melisandre is heavily associated with the colour red - her eyes, her clothes, her hair, her God - 'the red woman'. She is the embodiment of RED. If Melisandre is the daughter of Shiera Seastar - Star of the Sea, she might be called Melony SeaSTAR. When she sees 'him' (Bloodraven) in her flames, Mel spontaneously starts BLEEDING, overwhelmed by the vision.
It's slightly ambiguous as to what actually triggers the bleeding, but the point is that it could feasibly happen again at the right time and place, with Azor Ahai's rebirth imminent. She would be the RED STAR BLEEDING.
So the most questionable thing here is Mel being Shiera Seastar's daughter. The problem is that we have so little information on Shiera - but we can speculate with what we have got.
Shiera herself can't be Melisandre. It doesn't tally with the scene of Mel in her younger days being called Melony, seemingly a slave. But we can look for links and clues that Shiera and Mel might be related - Melony being the daughter makes the most sense in this scenario (later). We also see a woman cry out Melony Lot7's name when Mel is a lot younger - it would fit that the woman's voice is her mothers.
Shiera was said to have a heart-shaped face, and this description is also given to Mel. A heart-shaped faced is a rare trait, only attributed to two other characters outside of Mel and Shiera, and one of those is related to Shiera. (Mel's possible glamour is explained down-thread btw)
Looking closer at Shiera's description reveals further striking similarities between the two: (credit pobeb)
"She was the greatest beauty of her age, a slender and elegant woman, slim of waist and full of breast... She had a heart-shaped face, full lips, and her mismatched eyes were strangely large and full of mischief; her rivals said she used them to melt men's hearts."
In comparison to Maester Cressen's description of Mel:
"Slender she was, graceful, taller than most knights, with full breasts and narrow waist and a heart-shaped face. Men’s eyes that once found her did not quickly look away, not even a maester’s eyes. Many called her beautiful."
Despite all the undeniable similarities, notice that Melisandre is quite tall, which is not something GRRM says of Shiera. This could be an indicator of Shiera and Mel being closely related rather than the same person. The descriptions we have of Mel make even more sense, and get really interesting, when we compare her with a potential father - Bloodraven (later) - nearly everything about Mel can be attributed to those two.
Shiera had an interest in prophesies, and nobody knows what happened to her. Perhaps she decided to go East, and was captured by slavers and sold on. This would explain why Melony, lot 7, was a slave long ago. Reasons for Shiera fleeing could be; to hide Bloodraven's lovechild from Maekar and others in a turbulent political time or demonisation of royal bastards in the Blackfyre era. Shiera might have tried to head to Lys, given her mother was from there. These scenarios make more sense if she had a secret child or was pregnant.
Tyrion reads three books on the Stinky Steward. The "most engrossing" is about a young slave girl in a Lysene pillow house. It apparently begins with her account of how she and her sister were taken by slavers, which might be a clue.
Mel seems to be very old. She looks young, but thinks of her days "long before Asshai". She needs to look young to be seductive/appear powerful etc., and the fact she seems very old makes a tie-back to D&E era possible. There is a further clue to Mel being older than she seems here;
Melisandre had practiced her art for years beyond count
Mel using magic to disguise her real age links in with Shiera and her Grandmother Serenei, who were both said to use the 'dark arts' to appear younger and possibly live longer. No doubt there might be some rumour involved here, but it could be a link/hint nonetheless. Mel's interest/aptitude with magic generally, might be a likening of personality with Shiera and Serenei - a kind of family trait.
Shiera wore an exquisite necklace with Sapphires and emeralds on it. This thread proved that every mention of sapphires meant that there was a secret going on - 26/26 times in the books. The most appropriate example is in AGOT, speaking to Ned, Tobho Mott was wearing a large sapphire necklace, and the secret here was Gendry's birthing. So perhaps there's a similar secret involving Shiera represented by a sapphire necklace. Shiera's sapphires, according to GRRM, happen to be STAR sapphires.
Speaking of Shiera's necklace, this was a striking characteristic that she was known for, and Mel has a character defining necklace of her own, just with a different jewel. This jewel, a ruby, is heavily associated with House Targaryen, of which Mel would be a blood descendant. The ruby also happens to be described as a RED STAR (later). The fact that Mel wears a gold choker again points to her not being Shiera, as GRRM has said she wouldn't wear gold.
One final observation regarding linking Shiera's necklace to Mel comes courtesy of pobeb; perhaps they like the same colours...
"Her favorite piece of jewelry was a heavy silver necklace of emeralds and star sapphires, alternating."
Mel PoV in aDwD:
"Her sleeves were full of hidden pockets, and she checked them carefully as she did every morning to make certain all her powders were in place. Powders to turn fire green or blue or silver.
THE NAME SEASTAR
Regarding the name Seastar. It's worth pointing out that this is more than a random family name. It was given to Shiera and it means 'star of the sea', as if Shiera 'was' a Star. Knowing this, it seems acceptable to describe Shiera or Mel as Stars. Why did GRRM tell us that Seastar meant 'star of the sea', and used the phrase interchangably? It's also such a curiously unique and standout name.
"Sweet Serenei died in childbed,...the daughter she named Shiera, Star of the Sea" (note GRRM doesn't call her Seastar at all in the ssm, just 'Star of the Sea')
There are two occasions on which Mel (and necklace) are described as being like a red star. This could be a further hint, and no other character is given this red star association.
Her eyes were two red stars, shining in the dark
Melisandre’s ruby glowed like a red star at her throat
There is also an instance of Shiera being sneakily linked with the red star bleeding, courtesy of the Dothraki's word for 'bleeding star'...
The Dothraki named the comet shierak qiya, the Bleeding Star
The only other mention of Shiera in the five books says that the Kingdoms 'bled' for her. Again, I'd argue that these are part of a clue trail leading us to Mel being the red star, rather than Shiera herself.
If we consider that the name (and the other clues) might make Mel a 'red star', all that's needed is for her to bleed at he right time and place. Given she bleeds in such a strange and standout manor in her POV, with no physical cause, it's not difficult to imagine it happening again (perhaps with certain triggers), which would make her the RED STAR BLEEDING.
And if the prophesy is correct, when the red star bleeds - Azor Ahai will be reborn.
Some associated thoughts below, I'll use spoilers to less confuse the thread... (don't miss this Bloodraven one, it really ties in)
BLOODRAVEN AS THE FATHER
PART 2 is here and concerns the manor in which the red star might bleed.
