Broken Leylands (SLurl) is home to some engaging caverns and where you find these entrances to the Underworld, you find dragons. At least when I was there the rocky nooks and crannies were crawling with these amazing reptiles. Being Irish, I can't help but be fascinated with them. Celtic dragons, of course, left the Isles during the time of Saint Patrick or were imprisoned by him. As the snakes return to Ireland, though, I fully expect the dragons to be seen again soon. Until then I'll haunt their homes in Second Life.
Special thanks to Kennylex Luckless for finding this spot to explore.
