Titivillus, on the account of the monk Grigoriy XI, had a very busy schedule from 1374-1376. In the manuscripts, an account is given of the demon's central role in the lead-up and aftermath of several wars. Among details arranged chiefly by Titivillus are the survival and ascension of Philip III, and policy eventualities intended to cause several world wars. The demon began in 1374, in the obscure nomadic 'court' of the friar-duke Mindell whose sect supposedly operated secretly in both the shadow of the Catholic church and one or more communities of the Coptic Orthodox. At the hidden meeting with Mindell, Titivillus had accepted a "basket of twigs" thought to actually contain effigies. In turn, Titivillus produced forged holy books from the Earth, which Mindell smuggled into monsteries where they were readily accepted without oversight from the church. From here, Titivillus traveled through the woods to a bog in the south of Denmark, to a great gated fissure in the earth. Here he laid the effigies, which would later be discovered by a would-be noble. It was also at this gate that Titivillus contacted several minor demons who proceeded to disperse southwards and wreak various deadly havocs for the next two centuries before the serpent gifted human minds with industrialization.
Moving southwest, the demon took refuge in a cottage and manifest as the apparition of a man who had once lived there. It was here that Grigoriy attributes uncharacteristic acts of direct violence to Titivillus - the demon is said to have killed several travelers who took refuge in its cottage. It eventually abandoned this cottage as a few in adjacent villages began to grow suspicious. Continuing west and south, Titivillus returned for a time to his more traditional spiritual role - albeit with furious comprehensiveness. Titivillus was now hitting every monastery, church, and religious gathering from the west side of Germany on into Aragon with subtle-but-vicious interferences in the text which led to strange localized deviances. These built into several vicious skirmishes and minor inquisitions. Finally, just prior to the spring of 1375 the demon came to Granada and enlisted an aide who helped to corrupt the works of Muslim scholars. Under cover of night on February 3rd, 1375, a pretender left by boat from Granada to travel to the Turkish empire with "corrections" which would decide the future order of the Ottomans.
Returning to Aragon in late February, Titivillus traveled from town to town with a band of lower demons disguised as men. They purchased several peasant children who gradually starved in their company, and the group left the bodies by the roadside where pieces were picked up as trophies by heretic cults. Information about some of these was later extracted by renegade monks as they hunted for individuals suspected of participating in the nocturnal rituals witnessed by local villagers. In May, Titivillus was witnessed performing conjurings in the center of a Norse town - a demonstration of some kind. Word of this scene made its way back to the church, though no clergy were present at the time to witness.
Grigoriy records that a further set of pieces were transported from hell into Christian houses, to be utilized for wicked deeds at later dates - daggers, hammers and nails, and strange items unrecognizable to humanity. It's thought that these were somewhat simpler in intent than the effigies, but had been nevertheless bewitched by the forces of the devil. After the Norwegian ritual, a small group of clergy were sent to investigate, but found nothing in the town square and few who could offer any previously unknown details. However, one man did direct the group to the body of a child found in a mummified state in a cupboard in an adjacent town. Over the next twenty years, these towns were the sight of numerous mysterious murders, thefts, and attacks - things that have naturally been forgotten by most, as they often are. As summer 1375 swelled, Titivillus was seen to move east to Novgorod, where the demon's activities increased in prominence - appearing to conjure at several festivals, and engaging with increasing fervour in his standard practice of poisoning literature with heresies - entire libraries. At the end of the fall, Titivillus wandered through the woods of the Teutonic state westward to again settle in the forests of Mindell's domain as the year wound to a close.
Grigoriy's account of Titivillus is unusual in its detail, as well as in the activities it details. It closes in early 1376 as the demon's activities reduced to his standard mischief. But the things he did in this short period seem to have had a lasting effect on human history.
