I've been working on getting iridium from Sheldonite ore, which took me far away from the mainland where the dragon is. However, I saw that a obsidian tower, as well as the crystal itself, spawned alone on one of the end's many asteroids. I'm currently using the Mindcrack Pack, but is this normal? I was wondering if any would spawn if I went far enough away, but reminded myself it likely wouldn't happen until it did.
