|Temeria has yet to speak its last.|
|- Jan Natalis during the Summit at Loc Muinne|
Jan Natalis (also translated as "John Natalis" in the games) was a Temerian constable and later on the commander-in-charge of the Northerners at the Battle of Brenna, one of the key battles of the Second Nilfgaard War against the Nilfgaardian Empire.
- It seems that every other person you meet took part in the last war against Nilfgaard. Such are the times in which we live. Yet we best remember those who made their mark in the annals of that conflict. John Natalis, Constable of Temeria, is one such person. Supreme commander of the cumulative forces of the North at the Battle of Brenna, Natalis fought valiantly, commanded wisely, and contributed vastly to the victory, despite being outnumbered by the enemy two-to-one. And he did not rest on his laurels after the battle. Instead, he pursued the foe, routing him nec nuntius cladis or nearly so, leaving but a few stragglers to flee beyond the Yaruga. John Natalis was honored richly for his deeds, and a square in Vizima now bears his name.
- After Foltest's death, Natalis temporarily served as a regent of Temeria.
- If Geralt chooses to rescue Triss:
- As a patriot and a soldier, he was the ideal, apolitical candidate for the position of interrex. These same traits, however, meant that he lacked the support of powerful nobles and thus could not speak with a united voice for Temeria as a whole.
- If Geralt chooses to rescue Anaïs and not give her to Radovid V:
- Natalis had fought many battles, but the one he fought for Temeria's independence at the summit in Loc Muinne was surely his most challenging. With King Foltest's daughter as his ward, he gained the chance to preserve the sovereignty of the state he temporarily governed.
Vernon Roche said that Natalis brought Temerian soldiers to defend the Dol Blathanna - Mount Carbon line, where they held the line for three days, but were soundly defeated on the fourth day, with most of the remnants of the army going underground, fighting a guerilla war against the Nilfgaardian forces, like Temeria's Sons in White Orchard.
In The Witcher 3: Wild Hunt, there is a gwent card with his image.
- In The Witcher, Jan Natalis never physically appears but there is a plaza in Trade Quarter of Vizima, called John Natalis Square, that can be visited by Geralt throughout Chapter III.
