Vraegar frowned, the expression on his draconic face was frightening, "Andar, I know your Tower would be something spectacular, but I don't think it should be able to hold back the Memory of an Old One. You don't need to lose more than you already have just to save me; I know how expensive a Magus Tower is; I won't be able to repay you for millennia."
"You are right on both fronts. My Tower is indeed spectacular, and it cannot hold back this Old One, not for long anyway, but it was never meant to. Before entering that Realm, I figured out that the Old One would be able to easily lock down space to prevent us from leaving, so I placed my Tower outside the realm while bringing part of it with me inside. In essence, I created a funnel through the blockade, and we can bypass the space lock without contesting the Old One in might. Do not worry about the cost of repairs; if we survive, I am sure that our father will reward me with greater bounties for saving your scaly hide."
