Billy didn't feel like waiting for Icarus to find the dungeon, so he looked around the base to find any place that would fit the entrance. It was supposed to be massive since it was supposed to spawn fire dragons, so… It would be pretty hard to hide. Still, there was no mountains or hills around, so they had to find an underground entrance… Most likely one had been hidden by some sort of magic. Since the mana level around was high, Billy didn't find any signs with his eyes… Still, he could check the entire area by using Earth magic to sense things around. In the end, it didn't take long…
"Found it…" Billy said.
The entrance of the dungeon was hidden under a random building that collapsed. Billy moved the things away by using Earth magic and Icarus eventually joined them. It was a pretty suspicious way to hide a dungeon, but on the case of an attack, the building would hide the entrance and that was what happened.
