Krell

Act Two: Episodes 5-19

Krell was busy adventuring, exploring the catacombs beneath the desert oasis, when he was abducted by demons seeking his blood, a portal opened up nearby, skeletal figures with long arms reached out and dragged Krell towards them, as he was shouting, down into the hell-scape on the other side of the portal.
To this day, Krell has never been sighted on sanctuary again.
