"03 - Collector [EX]

The ability to acquire items of higher quality. It's the good luck of frequently obtaining even rare items, but because it only applies to Gilgamesh himself, it does not bless the Master.

Gilgamesh is a collector of treasure. "I collected all the treasures of the earth," is Gilgamesh's favorite phrase, but that is not a metaphor. He collected and stored away a sample of all the technology that was developed during his age and sealed them.
That which Gilgamesh stored, rather than being treasure, is "the origin of the intelligence of mankind" itself. If it does not exist in Gilgamesh's treasury, then it is "something produced by a new breed of humanity, according a completely new concept," "something made from the technology of the culture born from the intelligent life from another heavenly body," one of the two.

For that reason, of course he has airplanes and submarines. The desires of the people from before Christ are not different, and it would not do for the crafts of ancient times when magic was in good health to be inferior to the crafts of the modern age. People generally realize the "tools of hope" that they dream of, and each time that occurs, it ended with them being confiscated by the king's hand."
