Farlands.

Farlands is a Minecraft world generation bug where the noise generator would break, generating broken chunks. Farlands would start generating at +12,550,824 / -12,550,824 along the X or Z axis.

This bug was fixed in Minecraft with the new world generator in Beta 1.8, but since 2Beta2T runs on Beta 1.7.3, it hasn't been fixed yet. This has led to many players wanting to experience this anomalous place for themselves.
