From the publisher: Each year, Klaus the Kindhearted takes off into the Astral Sea with his bag of gifts on his magical train to visit all the good boys and girls across the cosmos. While he's gone, Mrs. Klaus tends to their home in a magical demi-plane. Every year, dark forces of frigid evil try to invade the Klaus' home and extinguish the magical flame that lights their furnace. If successful, Klaus wouldn't be able to find his way home and the vile Snowman could send his forces out to blanket the world in ice. Normally, the magical wards set about the property would protect it, however, this year they've inexplicably failed. Now, the Snowman's unending blizzard and frozen forces are marching on the house. Unless a brave few hold them off, Yuletide could be ruined forever.
