Redcap / Wintercap (New World) are fey entities allied with the group in the gesta (campaign-cycle) Gary TNW. “Redcap” is a creature of folklore: a malevolent goblin with a cap dyed in blood.
At the end of the gesta, Redcap escapes with his allies aboard the Train of the Laughing Vulture, departing from Iron Mountain. Iron Mountain is also the portal-hub of the cosmic entity Graz’zt (“Graz’zt” or the Iron God), which he shares with the fey.
