The Sentinel's Playground was built around 2010. It became a cluser that had meaning. The cluster was named after a song known as "The Sentinel" By Judas Priest.
The server was also home to All fear the sentinel Deathmatch. Both of these had meaning in the songs chours. Those lyrics were:
- SWORN TO AVENGE!
- CONDEMN TO HELL
- TEMPT NOT THE BLADE
- ALL FEAR THE SENTINEL!!!!
