you were well known among the people of Gallifrey, before the Time War. When the Time War happened, you were put into a sleep in which the 2 brothers must reunite in order for you to wake.

you are currently resting in the ruins of Gallifrey, in your Crypt, your silver eyes closed. your not dead, yet, your just sleeping. Your brother is in the TARDIS, tracking your Coordinates. he's heard of the legends surrounding 'the Memories', 'The Keeper', 'the Ancient one', and 'the one who Remembers'. and, most recently, 'the Sleeping one'.

[the legend of 'the Sleeping one': the 2 brothers must reunite. and the moonchild's staff of names must be found in order for the last moonchild to wake. ]
