Astram

Astram (アストラム) is a planet that had developed an advanced knowledge of karakuri technology. The source of the knowledge was a special dark stone within the planet, containing the power of a medal containing the knowledge and information of an ancient space weapon known as the Raging Arrow within it.

After discovering the importance of the Raging Arrow and partner weapon, the Grieving Bow, from a third prediction of the Evil Will released by meteors, Boss Tau Zant of the Jakanja instructs Seventh Spear, Sandaaru to go to Astram and gain the Dark Stone with the Raging Arrow medal within. Sandaaru easily crushes the planet and ultimately destroys it, taking the Dark Stone to Earth to join with his leader and begin working for his boss' ultimate plan.
