Apexis Monument
Apexis Monuments are ancient crystalline structures left behind by the Apexis, a long-dead arakkoan sect. Apexis Monuments are surrounded by four smaller Apexis Relics.
Apexis Monuments work very similarly to Apexis Relics in that they use colored lights to activate its vibrations. However, it requires 35 
[Apexis Shards] to activate, and requires four people — one on each colored button — to run it, although it is possible for 2 people, stationed opposite each other between buttons, to operate it in a pinch. After six rounds, or once your group fails a round of the activation, an Apexis Guardian — a construct left to defend the Monument — will appear and attack. Defeating it is the objective of 
[20-30] Guardian of the Monument.

Notes and trivia
- All it really takes is one player. You just fail the colored lights "test" and a Apexis Guardian will appear. Just make sure you are strong enough to defeat it.
- The Ancient Prism depicted in [20-40] What the Draenei Found might be a reference to the Apexis Monument and its mechanics, as it changes color and is described as some kind of possible "depraved torture device".
