The ABD was sneaking through the sewers.
She had been brought back to life by means unknown to her and had decided that she might as well take the opportunity to get her vengeance.
Those damned elves would be going down HARD when she was done.
She was going to assemble a small army of elite minions before swooping across the elven homelands in a blaze of fury, and they would all pay, every one of them.
And what better minions than her own offspring? Not only would they be loyal but they would also gain additonal strenght from being part dragon.
Off course, to achieve that she needed to gather "Materials"
And thus she was going through the Azure city sewers on a little "Goblin hunt"
It was also an added bonus that Goblins made a darn fine meal…mmmm tasty.
