Jeffbase II

Backstory
Jeffbase II or Jeffbase 2 was a base established by 99Y at 30m30m shortly after he arrived there. You might think that it was an impressive base with 99Y afking there for 20+ days, but it was actually incredibly unimpressive only having an afk fishing area, a hole going down to bedrock and an unfinished drain nearby.

Legion Stash
In early May 2018, 99Y got word that Hayden2003 had discovered his nether roof exploit and was heading to 30m30m. Following this, he moved the entire stash from the 30m30m legion base to Jeffbase II for temporary storage. Shortly after, he moved the stash to the location which would eventually become Jeffbase III.

Destruction
The base was mostly blown up by 99Y on May 15th 2018 so that Hayden2003 wouldn't get to destroy it.
