If it comes to it, I could use Mammon. Submaterium &c. works well with space and doors, plus he's magic.

But you could just have one parent. Mortal/God pairs produce demigods too.

Ya, but mortal/god Demis are much weaker than god/god Demis.

I suggest Vowzra ([@Kho]) and Belru ([@The Omnipotent Sphere]), or if that doesn't work, Belru and Mammon ([@Fabulous Knight]). You could also do Ull'Yang ([@Vec]) + Belru or Ull'Yang + Mammon could also work.

Failing those, Mammon + Vulamera (me!) MIGHT work, if we stretch our imaginations. We could say that Vulamera's intelligence combined with Mammon's submatterium created a Demigod who could control the Submaterium and had the intelligence to manipulate it into creating portals. Personally, I would [b]LOVE [/b]for Vulamera to have another Demigod :D

Ultimately, it's up to you. Just think about who you want to interact with.
