After assuring himself that all was secure, Tristan seated himself in a chair which stood in the centre of the chapel. The place was dim and ghostly. A red lamp burnt before the Blessed Sacrament, and from the roof of the chapel hung another lamp of bronze. The light was turned low, but it threw a slight radiance upon portions of the mosaic of the floor. Tristan unbuckled his sword and placed it ready to hand. The whole of the Basilica was hushed in sleep. There was a heaviness and oppression in the air, and no sound broke the stillness in the courts of the palace. Memory flared up and down like the light of a lamp, as Tristan pondered over the changes and vicissitudes of his life, with all its miseries and heart-aches, as he thought of the future and of Hellayne. Danger encompassed them on every side. But there had been even greater terrors when he had plucked her from the very grip of Death, from the midst of her foes. And then he began to pray, pray for Hellayne's happiness and safety, and his whispering voice sounded as if a dry leaf was being blown over the marble floor, and when it ceased the silence fell over him like a cloak, enveloping him in its heavy, stifling folds. He had been on guard in the Lateran before, but the silence had never seemed so deep as it was now. His mind, heated and filled with the events of the past days, would not be tranquil. And yet there was a deadly fascination in this profound silence, in which it seemed his own mind and the riot of his thoughts were living and awake. What, if even now some lurking danger were approaching through the thousand corridors and anterooms of the palace! For on this night the enemies of Christ were abroad, silently unfurling the sable banners of Hell. The thought was almost unbearable. It was not fear which Tristan felt, rather a restlessness he was unable to control. Although the night was no hotter than usual, perspiration began to break out upon his face, and he felt athirst. The fumes of incense that permeated the chapel, increased his drowsiness. With something of an effort Tristan strode to the door and opened it. In the corridor two men-at-arms were on guard, one standing against the wall, the other walking slowly to and fro. The men reported that all was well, and that no one had passed that way. Tristan closed the door and returned inside. He walked up the chapel's length and then, his drawn sword beside him on the marble, knelt in prayer before the Blessed Sacrament which he had come to guard. There, for a little, his confused and restless mind found peace. But not for long.
