World Tree

Unlike sources born from earth veins, the world tree comes from the void that flows ether. Which is considered to be the fifth element after the four primary elements of water, fire, earth, wind; ether or rather the intermediary substances in outer space are massive amounts of mana that have been blown. The world tree then uses its foliages, or rather its root, or rather, terminals to suck mana from the flow of ether. And then, the released mana are sent deep into the ground which activate earth veins of the earth. With the spirit seer skill one can see the body of the world tree shine dazzlingly and with concentric circles of light rings spreading like ripples around the tree branches. That light is the figures of the spirits who have gathered on the leak of the mana flow that's going from the sky to the earth.

When is inside the world tree at 300 kilometers high above the ground, which would exceed the stratosphere the gravity remains at 1G; the world tree is able to do this and hold its immense weight through the countless branches of the world tree that drive themselves into the adjacent sub-space (Isa Plane) like anchors which help distribute the world tree's weight and support it.

The management of the world trees scattered around the world are left to the elves; the greatest threat to the tree is greed where people and countries with knowledge of the possible uses of the tree could try to make it theirs. If this leads the world--greatly dependent on these trees--to destruction because of mismanagement of these trees divine punishments will fall from the gods.

Trivia

 * The first mention of the world trees is when Pochi request Satou to read a picture book to avoid falling asleep.
 * The world tree regards high elves as one of its parts and it has been like that since their beginning.
 * Every world tree has eight light ships each, but Boruenan only has four left. The goblin demon lord was rampaging a little over 100.000 years ago. Heroes didn't exist yet at that time, so three light ships were destroyed before the demon lord could be defeated. Then another ship was given to the Saga hero as a reward for exterminating the demon lord.  It's now passed down through the next generation in the Saga empire.
