As Xenon had predicted, they soon came upon a cavernous entrance etched into the base of the volcano. The jagged opening seemed to have been formed overtime, as a result of the rock that had been weathered due to age and repeated contact with high temperatures. The entrance was just large enough to fit three people standing side by side and it dug in deeply into the volcano, such that it had created a tunnel passageway of some sorts.
From first glance, one could only see the darkness stretching on and on within the depths of the cavernous opening, and it was unclear if it led to a dead end further in or if it would lead right into the heart of the volcano itself. Xenon was certain Menarx was in there and this meant at some point, this entrance or some other entrance had been used to get into the volcano as the caldera above was not a feasible way in.
