The Soul-retaining Chain is approximately two meters long metal chain.
When held in hand, it feels quite heavy.
The unique feature is the surface of the chain, which emits a faint blue glow.
It resembles the burning of the Soul Flame.
This color is often seen in the Viscera Museum.
There's nothing special about the chain itself, but the described effects are indeed quite surprising.
Most heroes, even the Dragon Queen,
dare to battle beyond their levels, largely because the courage granted by the Hero's Altar.
Being able to resurrect, they fear death less, as it just costs some materials to resurrect.
Moreover, to breach a city and destroy the Hero's Altar would mean a power struggle.
Such wars are generally hard to achieve.
But if, one day, they realize they can no longer resurrect, that everyone has only one life,
the situation would change drastically.
Heroes would no longer be reckless and would have to be more cautious in their actions.
