The dark portal that was usually a dungeon's entrance grew bigger in size with each spell's activation. The main circular center inside remained the same size; it was the dark smoke or energy constantly emitted by the dungeon that was getting bigger in size.
Till all the spells of Ilvanya were activated, nothing abnormal showed up other than the dungeon entrance reacting slightly. Damian had copied all the spells without question for doing this ritual again on his own. The elves knew he could copy any spells, and once they revealed this method, it would be forever in his hands.
Land-breaker could also do this, though. So it would have been revealed to him sooner or later, even if the elves refused to help the research center. This way, at least they could score some points with him and Sanctuary while showing the research center members how helpful they were, unlike others.
