Do you think the Tulnar should have real world artistic influences? A specific one? A mish-mash? Or something truly unique? What do you envision when you think of the Tulnar?
All the other 8 races have an artistic influence based on real world cultures.
- The Kaelar have a European racial influence.
- The Vaelune have a Middle Eastern racial influence.
- The Dünir have a Nordic cultural influence.
- The Niküa have a Polynesian influence.
- The Ren'Kai have an East Asian influence (perhaps even mostly just Japanese)
- The Vek have a Mesoamerican racial influence.
- The Empyreans have a Greco-Roman imperialistic feeling.
- The Py'Rai have a Navajo Native American influence with woodland architecture.
From the wiki about the Tulnar (emphasis mine):
They're a culmination of the leftover races, not just the leftover major race populations, but the leftover minor races as well; and that's what gives them their attributes that are bestial, or reptilian, humanoid; and that players can use sliders to influence the visual representation of. But in a similar fashion, their cultural markers are also going to be a culmination of different influences, so they're very differently constructed culture than what is found in the other eight races.
Combined with what we know of the Underrealm and what it looks like, I am honestly drawing a complete blank when it comes to any artistic influence of the Tulnar. I hope someone at Intrepid has a clear vision. Or that one of you do.

It would be cool to see something completely new I suppose, but I would be ok with some real world influences as well. I just don't see any.
