Oath Dagger

Within every Kaharan household, nestled amongst cherished heirlooms and family treasures, lies a dagger, not simply just a knife, but a symbol of the family's honor. It may be a simple blade passed down through generations, its hilt worn smooth with age, or perhaps a finely crafted knife, In rich households the dagger may be a more oppulent, studded with gems or coated in gold. Regardless of its shape, every family has at least one, its blade made to hold the weight of a soul's oath, a whispered promise to the god's themselves.
Oathbinding
When one of the kaharan people feel compelled to make an oath of profound significance – a vow to protect the innocent, avenge a fallen kin, or uphold a sacred duty – they embark on a solemn pilgrimage. Their path leads them to visit the temple of the Goddess of Death, for she keeps count of all promises made - those taken lightly, those fulfilled and those broken.
Within the temple's hushed halls, before the eyes of a priestt, the individual presents the Oathblade. A priest will question the one bringing the blade, affirming one is sure - for taking a vow upon one's very soul is not a decision to take lightly .
If the oath-maker confirms their resolve, he is lead into the inner chamber.. With a trembling hand, the oath-maker draws the blood of a sacrificial animal, their own blood in the most sacred of oaths, and uses it to inscribe the oath's purpose upon the blade. This sacred inscription, a testament to the unwavering will of the oath-maker, is then slid into the very stone of the temples walls itself, is then embedded within the temple walls, hidden from all eyes but the godess herself. Only the hilt, bearing the family name painted in blood, remains visible.
The Chamber of Oaths:
In some of her grander temples, entire chambers are dedicated to these Oathblades. Row upon row, the hilts of countless blades stand a silent vigil, each bearing the name of a family and the silent promise of an oath. These chambers whisper of the sacrifices made, the burdens borne, and the unwavering resolve of those who dared to bind their very soul on a promise.
There can be multiple oaths made within an extended family, in which case a new blade is chosen by the one taking the oath. Though the blade itself may be returned to the family after the oath has been fulfilled,some donate it to the temple as a sign of respect for the godess.
Whispers from the Afterlife:

Rumours speak of those who, bound by the weight of their oath, have been granted a blessing to defied even death itself - for a while. Driven by an unyielding will, they refused to enter the river of souls, their spirits tethered to the mortal plane by the unfulfilled promise. Those few who met one of these rare These rumours are often dismissed as mere superstition, but the Godess and her priesthood certainly seem to differ on the subject.
