As the others advance towards adventure, Acanthus stands there, studying the broken hunk of rock, shaking a finger at it as she thinks.  "This..." she says, seemingly to herself though it's loud enough for all to hear.  "This could be valuable.  Lost most of its power, but it still has some real magic to it.  Could be studied, or maybe salvaged.  I think it used to be some sort of portal, but it's definitely the kind of thing Allustan would be interested in... the last explorers probably ignored it for being heavy and looking like broken furniture."<br/><br/>She begins inspecting the mirror closely, trying to see what it would take to move it without destroying it, and actually begins addressing the team.  "We should pick this up on the way out, if we can.  Haul it out of here.  It's not exactly going anywhere."
