Now the Sons of Usna were very dear to Lavarcam: and Naisi was dearer than the others. And rising up she went to the Red Branch, where she found Naisi and Deirdre with the chessboard between them, playing. And she saluted them affectionately: and she embraced Deirdre, and wept over her, and kissed her many times with the eagerness of her love: and she kissed the cheeks of Naisi and of his brothers. And when her loving greeting was ended, she said:--"Beloved children, evil is the deed that is to be done this night in Emain: for the three torches of valour of the Gaels will be treacherously assailed, and Concobar is certainly resolved to put them to death. And now set your people on guard, and bolt and bar all doors, and close all windows; and be steadfast and valourous, and defend your dear charge manfully, if you may hold the assailants at bay till Fergus comes." And she departed weeping piteously. And when Lavarcam had returned to Concobar asked what tidings she brought. "Good tidings have I," said she: "for the three Sons of Usna have come, the three valiant champions of Ulaid: and now that they are with thee, O king, thou wilt hold sway in Erin without dispute. And bad tidings I bring also: Deirdre indeed is not as she was, for her youthful form and the splendour of her countenance have fled from her." And when Concobar heard this his jealousy abated, and he joined in the feasting. But again the thought of Deirdre came to him, and he asked:--"Who now will go for me to the Red Branch and bring me further tidings of Deirdre and of the Sons of Usna?" for he distrusted Lavarcam. But the Knights of the Red Branch had misgivings of some evil design, and all remained silent. Then he called to him Trendorn, one of the lesser chiefs: and he said:--"Knowest thou, Trendorn, who slew thy father and thy three brothers in battle?" And Trendorn answered:--"Verily, it was Naisi the son of Usna that slew them." Then the king said:--"Go now to the Red Branch and bring me back tidings of Deirdre and of the Sons of Usna." Trendorn went right willingly. But when he found the doors and windows of the Red Branch shut up, he was seized with fear, and he said: "It is not safe to approach the Sons of Usna, for they are surely in wrathful mood: nevertheless I must needs bring back tidings to the king." Whereupon, not daring to knock at the door, he climbed nimbly to a small window high up that had been unwittingly left open, through which he viewed the spacious banquet hall, and saw Naisi and Deirdre playing chess. Deirdre chanced to look up at that moment, and seeing the face of the spy with eyes intently gazing on her, she started with affright and grasped Naisi's arm, as he was making a move with the chessman. Naisi, following her gaze, and seeing the evil-looking face, flung the chessman with unerring aim and broke the eye in Trendorn's head.
