Can we have magma pools/rivers in that new biome?

I think it would be cool if it's an area where all dragonfly lavae reside as well, not ready for fighting but generally it would have a bit of lore where tf does the magma on surface come from. 

A great place to revisit and to use solutions to deal with extreme heat, more uses for ice hat and chilled amulet. Environmental hazards in caves are great addition imo if they would bring use to certain situational items.
