The Grotto

The grotto is the name given to a sanctuary created by a blind terramancer who once resided at the Xavier Insitute, but has since moved on to seek further enlightenment and inner peace elsewhere.

Physical description/History(Earth 1235) (Year 2)

 * The Grotto is technically not even really a true grotto at all due to the only warer present being as a result on condensation from the cooler air within relateve to outside.
 * The Grotto's geo-physical location was never specifically determined other than it is on the grounds of the Xavier Institute.
 * The Grotto was created artifically with terramncery abiltiies as it's opening is typically submerged or toherwise masked by dirt and grass
 * The walls are made of stone and have saying carved into them (with tewrramncery) in multiple languages, some still spoken, some long dead.
 * The Groto is supplied with fresh air to avoid aspyiation by a series of vertical shafts to the surface who's openings are shield to prevent rain from coming down the shafts as well as camofaluged so as to not give about their presence and thus the presence of something abnormal below ground in that immediate area.
 * As the terramancer who created it was blind, while it was used by him, there were no light sources within it.
 * On insistence by The Core for security reasons there is a deeply submerged communications cable and a intercom speaker within the Groto.  There was however never a microphone or means of the terramancer responding directly nor was there any sort of visual sensor within The Grotto.
 * The Terramancer moved on seedk enlightenment elsewhere and left The Grotto hidden but completely intact.
