The Cloak of Innocence is a magical object kept at Blackwell Keep.
If somebody is new to a preserve, has caused no harm, and intends no harm, the cloak creates a powerful shield around them and any traveling with them. Even if the companions are scoundrels.
It was crafted by the wizards who first designed the preserves to provide complete protection to neutral visitors. It draws on the power of the treaty that founded the preserve, thus if the entire sanctuary fell so too would the power of the cloak.
If anyone under the protection of the cloak harms a creature or steals something, the protection is forfeited for all.
The cloak adjusts to the size of the wearer and changes from silvery white to black if the protection it can offer is revoked. The cloak will not work for someone who has previously done wrong.
