The Fortress of Time

The Fortress of Time is a structure found under the Landing Site. Once Martian Madness is complete, inactive blocks will lead to a passage way which leads to a portal. Then, the player will be teleported to the beginning of the Fortress of Time. It has no enemies. The music is the Purity daytime theme but only the main melody and slowed down.

Mounts cannot be used in the Fortress of Time. Pressing R or using one will dismount it as soon as it is mounted.

It is composed of Platinum Blocks.

Hazards
Intense use of blue and red pressure plates that either lead to traps with portals that do 9999 or solve puzzles.

Intense use of levers to complete puzzles.

High use of switches that either complete a puzzle or spawn a Time Boulder, a cyan glowing boulder which does 950.

Sporadic use of timers in "spleef arenas" in which players must transverse a changing landscape, or they fall into a Warping Portal, warping them onto a destination

Medium use of spikes, mainly wooden spikes

Sporadic use of lava traps, mainly triggered by a red pressure plate

Medium use of "quicksand pits", where the sand changes, causing suffocation. Red pressure plates lead to a normal piece of terrain, but after pressing the plate the terrain changes into the quicksand pit.

High use of time blocks, which change the time. Required to solve Day, Dusk, Night, and Dawn puzzles, using the day block, only solid during day, and same goes to the dusk, night, and dawn, which are only solid during their times.

Only one maze, at the very end, containing all of the above.

At the end is a sword-in-the-stone. Pulling it (using B to interact) with 500 or more max HP and text will say in cyan "Thou has done excellence to enter to the trial of time. Thou shall be honored a reward", and reward you the Terra Blade, and teleport you back to your spawn, at 5:00 AM. Less than 500 max HP will reward you an Adamantite Sword.
