The Obsidian Tower
The Obsidian Tower is the current spawn of the World, the current spawn being third spawn.
Description
The Obsidian Tower has a bedrock floor with obsidian walls and a crenellation around a glass roof.
Versions
First Version
The first version of the Obsidian Tower had an open roof that allowed new players to climb up to the top and walk across the crenellation and glass roof (and jump off, falling to their deaths). The Skyrail did not reach the Obsidian Tower at this time.
Second Version
The second version of the Obsidian Tower also had an open roof but the crenellation changed from bedrock to glass in material. The Skyrail reached the Obsidian Tower and had a very basic bridge between the Skyrail and the tower. Later, a wall replaced the basic bridge to the Skyrail because of an exploit that allowed users to jump around the doors.
Third Version
The third version of the Obsidian Tower closed the tower's roof with glass on top, around the edge of the topmost obsidian, and glass panes in-between. The Skyrail bridge became a Skyrail station, closed off to anyone without the Towny permissions, and for the first time the iron doors permitting entry from the east and west were closed with iron blocks. Iron blocks to the north and south representing doors along with pressure plates to the north and south were also added.
