Stronghold

A stronghold is a gateway towards entering the End dimension. Introduced in Beta 1.8, there were only 3 in the Minecraft world prior to 1.9. However, after 1.9 there were 128, and (since 9b6t started up following version 1.9 release), this is the count of how many there are on the server.

Closest Stronghold to Spawn
The clostest stronghold to spawn is widely used by the 9b6t playerbase. It can be accessed using a nether portal on a branch of the X+ nether highway. The portal is currently inside a obsidian room due to constant griefs destroying the rest of the stronghold and island above.

Other Strongholds
There are approximately 10 other strongholds spread out around the greater spawn region. These can easily be found by imputing the world seed into a stronghold finder. They have been used in the past as stashes for the donkey/end portal dupe. Most, however, are still widely ungriefed and unexplored.
