Tregin looks to Arsa and gives him a toothy smile. "I think I might have found an answer to the why. But first Ilestaem show everyone what you have found and tell them what you need done."
The man looks to the half-orc like he had just told some big secret but then shrugs and mumbles, "Very well."
He moves to the map and motions for everyone to gather round. He puts on a stark expression and starts to speak as if giving a lecture to a group of students.
"As you all must know, the land all around here was once at the bottom of a great sea. That sea was sailed and fished by our forefathers for more years than we have been on this world combined. And in one brief night the sea was gone. As if some great giant had come along and drank it all in one gulp. Or so the myths say."
He looks to the map and points at each of the pyramids. "These three pyramid's were the only man made structures found after the water was gone, and indeed they may not be man, or orc made at that. They may have been made, if what I have discovered is true, as focal points for an elaborate spell that somehow transported all the water to another plane."
He waits a moment and then his fingers trace small lines drawn on the map between each of the three pyramids. The lines are thin and faded as if added later. Then he moves to the key of the map.
"And here. Here is what I thought might have been a warning, but after translating it I am not so sure." Ilestaem says reading and mumbling. Looking up and into the eyes of each of you he continues. "It says - 'The key in three, shall not be revealed by thee.' - I think that if we can discover how the pyramids work the power they hold would be the greatest in all the world."
