The thre weapons were pluton, poseidon and uranus ... So I think Nidhogg is a separate entity
I just read a little more on nidhogg and I think it is the dragon on the adam tree in the wall mural
Oh. I see.
That's why it's form looked so familiar! Thx XD
Couldn’t it be like anti for ancient weapons? Remember how Tom’s blueprint of Pluto was actually a blueprint that could stop Pluto?
I'm not sure, but... is Nidhogg one of the 3 great weapons, like Poseidon? Or perhaps the Guardian to the third weapon? Imu seems to recognize it.... And, dare I say, they look lowkey scared...
