Sehir Halil is one of the vizier in Turkiye Stratocracy. He's Mahmut's surrogate grandfather.
He's an elderly man with plump body and relatively short stature. He has white hair befitting of his age. His outfit mostly consist of green coloured accessories, such as his robe, his turban's decorative jewel, and beard band.
He's known as a noble man who has earned a great amount of respect among his colleagues in Divan. Even the hardliner pashas such as Zaganos have a great deal of respect towards him despite their differing perspectives, as shown at the time of his death announcement which devastated a lot of people.
It has been shown multiple times that despite his jolly and cheerful exterior he's also not a naive man, as he frequently admits, albeit begrudgingly, that Turkiye can't keep silent after all of the troubles Baltrhein has brought upon them. This stance became more apparent with Mahmut's participation in Divan, as he often give his support to Mahmut's ideas to fend off Baltrhein's invasion plans.
As a vizier, Halil has what it takes to become a general: charisma, knowledge about the art of war, and overall decent ability to govern a province. However, it seems that his specialty is Civil Engineering, having built some of Turkiye's famous public places such as Halil Pasha Bazaar in Oasis City. It's also mentioned that Zeki Pasha is his disciple.
It's known that he had joined the war twelve years before the main storyline leading a counter-attack and won the war. At that time, he managed to fend off General Pineau's advance to the Stratocracy, but failed to prevent Tughril Village's destruction. While he was roaming on the obliterated village, he found a 5-years-old boy who turned out to be Mahmut, the single survivor of the genocide. Looking at the devastated child, he promised to prevent war to happen again since that time.
- He's most likely based on a real-life pasha in Mehmed II's period: Çandarlı Halil Pasha the Younger. Both are reluctant to start the war, albeit for different reasons.
- Sehir means "City" or "Urban" hence the title given to him "Urban General".
