The Sylvven Tower is traditionally the highest point of any castle, recent additions to Hogwarts castle now overreach the much older tower.

James Potter 1Edit

After Merlin’s return, he demands a meeting with the “Pendragon”. The Sylvven Tower is the site of the meeting between Prof. McGonagall (dressed in her flame red robe as the Pendragon of Hogwarts castle), Prof. Franklyn, Harry, Neville, James, Ralph, Zane and Merlin and his contingent of wildlife. After much heated discussion, Merlin concludes that he has been wrongly returned, the current world is no place for him and, taking his leave, vanishes.
