An idea I have is that the Goddess Clan equivalent to the second demonic mark that the demonic royal family has, is ''light wings''. Now hear me out, I actually thing it's a strong probability that this is the case. We already know that Meliodas and Zeldris, royals and sons of the Demon King have second demonic marks which boost there power. Meliodas and Zeldris base without it seem to be 60-61k (excluding AM), and with it possibly AA tier (90k) or even higher (100k max?). What if Elizabeth and by association her mother, the Supreme Goddess have light wings which temporarily boost their power or a singular spell to a higher level than their base, a similar mechanic to the second demon mark respectively? If we consider Elizabeth's greatest feats.. both light wings are present in them, which is an odd coincidence..: Spoiler: Chapter 97 - 4 light wings Besides the Indura feat, this chapter still holds on of Elizabeth's most impressive displays of magical power. Not only did she express 4 light wings which rejected dark nebula whilst damaging Ash-Grey-Hendrickson, she also healed an entire capital and city of people. For bonus points, she even enabled nature by giving life to plants and other similar things. And all of this was done when she didn't have any memories or conscious awareness of her own power. Apparently, her PL at this time was ''1925'' but given how this feat happens, it makes me believe more that these light wings act as a temporary power-up. Spoiler: Chapter 208 Elizabeth greatest feat is being able to almost individually purify the Indura who were able to fodderize the Four Archangels (except Mael) - given how these light wings express 8 wings instead of 4 this time, illuminated the battlefield in similiar concept to Elizabeth's 4 wings (but much greater) and made her spell very powerful, it shouldn't be just there to make Elizabeth look great right? Otherwise the Four Archangels would've gotten it by now, especially Mael or Ludoshel. I believe that these light wings are the equivalent of the second demon mark which temporarily power up the Goddess who constructs these wings. If Elizabeth was at 60,000 as a Goddess or even AA tier - these light wings could possibly push her up to AA tier or even higher (100k+) and considering how Elizabeth's PL is largely magic, would explain the tremendous power of ''Let There Be Light''. I don't think it's too stretched. Both times Elizabeth did amazing feats of healing or purification these light wings were present, and they were exclusively shown by her only - making me think it's the equivalent of the second demon mark, hence an exclusive power up to the Supreme Deity's daughter, Elizabeth Thoughts?
