Yggdrasill Tower

was the Japanese headquarters of Yggdrasill Corporation in Zawame, the most prominent feature of Zawame's cityscape.
==Overview==
The tower is shown to have an executive office and conference room on one of its higher floors and a basement laboratory where scientists and researchers study an artificially stabilized crack to Helheim Forest and conduct experiments on Lockseeds. 
It is revealed that the tower is equipped with laser turrets for defense against any Inves attack that occurs near it as well as a shield for cloaking the surrounding airspace. However, this is just a minor counter, as revealed by Sid to Kouta, the ring around the tower is a scalar-electromagnetic weapon, which Yggdrasill would be willing to use to burn Zawame City to the ground with just a press of a button, as a final defense against the spread of Helheim's plants to save mankind itself. To prevent the news of Zawame leak out to the media, there is also a Master Intelligence System located at the basement which only Ryouma Sengoku can use which can cut off the whole communication system of Zawame and create dummy footages at security camera, it can also be used to locate the Armor Riders and Overlords.
It is also revealed that there are many secret entrance which can allow people to enter the Tower with some of them are located outside the Zawame City as a precaution, though these entrance were armed with automated Tulip Hoppers and Suika Arms as a part of security system which is not able to disarmed them externally.
In the past, it was revealed that Yggdrasill Tower's spot was originally the location of Mai Takatsukasa's family shrine where she would pray at the sacred tree (which was actually a tree from Helheim) until said company had bought the land and used it's tree for the portal to Helheim. While Kaito Kumon's family house was also originally located near to it until it was bought and bring down by the company.
After Kouta realized the truth of Scalar System, he destroyed the system as Kachidoki Arms, causing the Yggdrasill have to change the plan to tackle the Inves by increasing the workload of Kurokagetroopers. After Redyue opened the crack, Yggdrasill Tower became a dilapidated ruin overrun by the plants of the Helheim Forest, with all the entrances within Zawame City are now filled with Inves and most of the system become malfunctioned except the Master Intelligence System which have been shut down by Ryouma beforehand until he reboots it after he returns to the tower with the aid of Beat Riders. This version of the tower was also seen in a possible future.
Yggdrasill Tower can be seen being demolished, three months after the clearing of the Helheim invasion following the dissolution of Yggdrasill.
