Obsidian Farming in Underground World Center Map??

[Piro De Lurker-[NW]-]

Anyone know where to find obsidian in here lol? It is the one thing we are having trouble locating and is a really long process to trek down here. Any help figuring this out is greatly appreciated.

From the Underworld, the best place to find obsidian is in the base of the shaft that emerges on the middle jungle island. It's one of the three exits at the ground level, the one that goes on a long bridge over lava; at the end of that trip, just before you'd have to climb or fly (if allowed) up, there's obsidian.
