Sir Lancelot's final memories of the Tower as he knew it last are all Darkness and Fire. But then, many of his own memories of Life and the War both carry a similar distorted taint. He recalls a Madness not his own, and a merciful Death. He recalls a brief respite-- a few lost days in his Master's company before Death took him once again. Suddenly, in that moment, as one struck by an arrow from afar. Or by some poison.
On his second rising, even the air of the place seemed changed, his own senses seeming to have lost their compass for a the space of a breath. Only that little time needed pass before he missed his Master-- and indeed, their bond is broken.
Berserker has wandered since as Mist and Shadow, and sometimes as Himself unseen. Content, for the time being, to watch as events play out before him. Without Kariya Matou, he feels less substantial, and less the more human Self that he had shared with his Master in this Place. Strange and Fae, he goes where his Will takes him.
The Graveyard - Here, he lingers by his Master's grave. He has avoided this Place, as it has nothing to show him that he does not already know to be true. Still, the sight of Kariya's grave marker is a painful one. A reminder that in the end, he failed his Master-- in every way a Servant can.
The Meadow - This was his Master's favorite among the Tower floors, and indeed it was here they met again after having been taken from the War. Here he is sometimes unseen, but today he stands beneath the false Sun, his back to the entrance, unguarded.
The Cathedral - Once a Holy Knight with a Blessed Weapon, Sir Lancelot does not enter the Sanctuary, but wavers just within the threshold-- as if in debate with himself over whether to enter or no.
Room 1-10 & Environs - Those he shares rooms with may find him sat on the edge of his bed or checking the contents of his Trunk. He may also be encountered in the dormitory hallways nearby.
