Can Gullveig of the Nordic Ascendant be used as material for the summon of another Gullveig?

Question

Gullveig of the Nordic Ascedant is a Link Monster who's materials say:

1 lvl 5 or lower Nordic Monster.

Does this mean the Gulllveig can be used as material for itself?

Answer 1

Does this mean the Gulllveig can be used as material for itself?

No it can't.

Link Monsters have no Level nor Rank. From the Wiki on Link Monsters, emphasis mine:

Link Monsters have a Link Rating in place of a Level or Rank. [...]

Link Monsters do not possess Levels or Ranks, therefore they cannot be used as material for a Ritual, Synchro, or Xyz Summon. Also, Level or Rank-modifying cards such as "Harmonic Waves", "Feedback Warrior", or "Xiangsheng Magician" do not affect Link Monsters.

As Gullveig specifically asks for a Level 5 or lower monster that means you can't use her as a link material to summon another copy of Gullveig.
