You were attacked by an horde of bandints and a bunch of monsters while you were searching for the mysterious treasure of Solaria, but also in search of finding the culprit behind the deterioration of the Fire Territory's oases, when the sand all of sudden begins to swirl all around you engulfing you in a tiny sandstorm which falls to the ground, revealing an all-too-familiar smile of nefarious glee.

"Oh my? What have we here? More than mere bandits this time, it seems."

You found the culprit.
