We have finally figured out the secrets behind the doors. Complex symbols must be drawn with Starun in order to energize a door, since the altars in front of them have no cavities. The Starun needs not be consumed for this. At least some great news. We have performed the several tests on the Library and the Shrine doors, which has led us to conclude that a Verge bearing a single Starun shard is strong enough to activate the doorway.
Mapping the ones we were able to activate, we have reached Spellenrune to recruit sufficient sages to help us decipher symbols that were not only in an ancient language, but coded as well. After putting in a hard working week did we discover the name of each door.
The Shrine of Heroes in Mithaurian, The Forge in Technokrest, The Hall of Titles in Spellenrune, The Atelier in Craftsmir, The Workshop in Basiliah, The Laboratory in Agadeera, The Armorial in Grymill, The Hall of Doors in Arcada, The Library of the Ancients also in Arcada and three other places outside cities called The Tower of Magic, The Ranch of Monsters and The Temple of Myridian.
