Collectible. Only undead champions may pass Charon to the Island. Others need to pay the price - sacrifice a champion to enter the Island.

"In the land of Frozen Fire, certain paths are not to be taken. Many places attract adventurous souls and glory seekers. Most of them never come back and become a cautionary tale. Frozen Fire lands are widely known for their brutal beauty, but many horrible secrets are hushed and kept between magical folks and ghouls of the locals. Some tales, however, cannot be kept secret for long. Many tittle-tattles about some islands that do exist and remain alone and uncharted for ages. Nor one or two brave and naive ones tried to step their foot here; not one came back to tell the story for themselves. Undead Island is one of those ominous places. Here, only undead ones could cross the gates. Everybody else has to face the carrier of death himself - Charon and deal with the consequences of stepping somewhere where they are not welcomed. The ultimate sacrifice has to be made. That is how this place remains the mystery for onlookers and the safe haven for undead ones."
