The curse is a punishment, basically all the human souls he killed/died because of him are in his hand. The god was most likely zeus but it's not stated outright. Seth wanted to break the curse and atone for his sins.
I have those same questions Σ( ￣□￣||)
- God from distant land was Zeus, brough in by Isis to defeat Seth as Plan B in case Horus lost the throne (but Horus didn't lose it): Maat convinced Zeus not to interfere with Egypt by offering to let Zeus use her husband Thoth's prophetic wisdom to solve some trouble back home.
- Seth' goal after dethroned was to both atone, recover his godhood. and save Anubis' life, all this by healing the human souls he had crushed in order to be able to make his cursed weapon (he had needed a cursed weapon because only a cursed weapon would work on the undead Osiris, and a cursed weapon could only be make by crushing human souls into pieces). To sum up: Osiris thwarted Seth's attempts to heal the crushed human souls by catching the souls himself, and forcing God Anubis to "eat" them. And now we know that this was all so that he could possess Anubis' body again, which had become harder to achieve again, ever since Anubis became a god, as apparently it's not as easy to possess another full god's body, as it is to possess a demi-god (like kid Anubis used to be)
- How Seth got the cursed bracelet: After Osiris possessed Anubis and tricked Seth into accidentally giving the curse to Anubis (by tricking Seth into cutting Anubis' arm with his cursed weapon), Nephthys used her godly power to split the curse on Anubis' arm into two, in order to help buy more time to save Anubis' life from that curse, and she used the other half to create the bracelet, which she then had teen Anubis give to Seth, so that Seth could help buy time to save Anubis by sharing half of the curse and thus being forced to find a way to break it. Seth got that curse on his arm when he accepted the bracelet that Anubis gave him, in the middle of the third match with Horus.
Literally bless you with all my heart you saved me a rereading
I take so many breaks reason this story I’m just so confused. So I forget why Seth’s arm is cursed. Who was that god from a distant land? What was Seth’s goal after being banished? How will Seth get his powers back?
