磁極

磁 = 兹 + 石 : The King of Chu (c) broke open a mysterious, previously sealed rock (石) made of porcelain (磁) just inside the space station's entrance (Ø2). The rock contained a magnet (磁) which as soon as the King of Chu picked up was so powerful as to attract a Nimitz class aircraft carrier (兹), crashing the hull of the space station.

极 = 及 + 木 : As Joan of Arc (ji) and Yuwen Huaji (及) pass over the north pole (及) at Christmas just inside the space station's entrance (Ø2) they decide to celebrate this moment by having a little contest. Between them there is a rather large Christmas tree (木) and they decide that whoever climbs to its top (极) first is the winner.
