dance with Catrina!

Makarios in Dead Man's festive form, on a Hallowed broom

The Day of the Dead is a small festival honoring the memory of passed companions. Grave-sites are decorated with flowers and offerings welcoming their spirits during this short holiday. This holiday is a nearly identical in-game version of the Mexican Day of the Dead.

Catrina

On this holiday, players can dance with Catrina to become transformed into a skeleton, earning them the holiday's only achievement, Dead Man's Party. Players will also be tasked with bringing a serving of Bread of the Dead to the grave of a returned ghostly spirit, whom can be brought into this world with a gift of Orange Marigold. As this holiday lasts only one day, it is an extremely minor event with only one quest that can be completed.

There is no special player title associated with this event. 

I got a shot of Mak in his Dead Man's festive form on a Hallowed Broom ;)
