There is an inactive sigil that leads into a cave next to Sir Drustin in Caliburn of Avalon. In Azteca, there is one inactive sigil opening into a cave in the Cenote near the MoonSkull Zombies, one that leads to a clearing in Zulton Docks, and there are 2 inactive cave sigils in Tierra de Brea; one near the entrance and one close to Cipactli's Cave.
Am I missing a quest for these sigils or something? I've looked around the whole worlds of Avalon and Azteca and I haven't seen one quest that leads into these caves (I've completed both worlds, mine you). I'm just a little on edge that I'm missing something to enter these areas. Are we returning to Avalon and crumbling Azteca for the next expansion or something? Or are these misplaced sigils that need to be removed? Thank you!
